In OpenVZ containers (and probably lx containers as well),
the diskstats entry is not even present. Use the "NoLogicalDrive"
introduced by Elizabeth Flanagan in such case.
This allows the bitbaking to occure within such containers.

This is the result of running the following over the metadata:
sed \
-e 's:bb.data.\(setVar([^,()]*,[^,()]*\), *\([^ )]*\) *):\2.\1):g' \
-e 's:bb.data.\(setVarFlag([^,()]*,[^,()]*,[^,()]*\), *\([^) ]*\) *):\2.\1):g' \
-e 's:bb.data.\(getVar([^,()]*\), *\([^(), ]*\) *,\([^)]*\)):\2.\1,\3):g' \
-e 's:bb.data.\(getVarFlag([^,()]*,[^,()]*\), *\([^(), ]*\) *,\([^)]*\)):\2.\1,\3):g' \
-e 's:bb.data.\(getVarFlag([^,()]*,[^,()]*\), *\([^() ]*\) *):\2.\1):g' \
-e 's:bb.data.\(getVar([^,()]*\), *\([^) ]*\) *):\2.\1):g' \
-i `grep -ril bb.data *`

tmpfs/encryptfs/(and most likely, but not confirmed)ramfs TMPDIRs
cause diskstats to choke. No device entry ends up in /proc/diskstats
for these fs types, which ends up causing the failure.
The short term solution is to exclude these fs types from diskstat
collection. Longer term we will want to see if we can collect
meaningful diskio for each of these, and other, use cases, but for
this cleans up Bug 1700.

This commit adds disk-io statistics functionality on a build
and per-task basis.
It pulls measurements for whatever partition TMPDIR exists on.
This data could be off if SSTATE_DIR and DL_DIR exist on
a different partition/volume.
Notes on what this pulls:
ReadsComp: Total number of reads complete
ReadsMerged: Total number of adjacent reads merged
SectRead: Total number of sectors read
TimeReads: Total number of m/s spent reading
WritesComp: Total number of writes completed
SectWrite: Total number of sectors written
TimeWrite: Total number of m/s spent writing
IOinProgress: Total amount of IO in progress at the time of
we look at /proc/diskstats.
TimeIO: Total number of m/s spent doing IO
WTimeIO: Weighted time doing I/O. From iostats.txt:
"This field is incremented at each I/O start, I/O completion, I/O
merge, or read of these stats by the number of I/Os in progress
(field 9) times the number of milliseconds spent doing I/O since the
last update of this field. This can provide an easy measure of both
I/O completion time and the backlog that may be accumulating."

Instead of using subprocess which is problematic, we should use platform
instead.
