lttng-tools: fix ptest

Since the upgrade to 2.8, lttng-tools' test harness silently succeeds
but doesn't actually run the tests.  This is because upstream made
some changes in their test harness:

https://github.com/lttng/lttng-tools/commit/83666813cad3142ceccb929ca9b44d0e9cf53bc8

Updates to address this include:
- drop now-irrelevant patch
- change the ptest-run make target
- remove indiscriminate search/replace commands from do_install_ptest
- copy entire build directory into PTEST_PATH and then remove unneeded files
- use lttng binaries installed on the system for the tests
- add lttng-tools-ptest runtime dependencies
  - lttng-tools itself
  - babeltrace, used by the test harness to process traces
  - perl modules required by babelstats.pl test script
  - procps (for pgrep, pidof)
  - gawk
- remove unnecessary chmod and munging of utils.sh script library
- remove checkpatch from ptest installation tree
- avoid path-munging of libtool artifacts altogether
- use more efficient find+sed patterns to munge Makefiles
- reduce test harness output to conform to ptest rules

On qemux86-64 and qemuarm I get relatively stable results, with
PASS/FAIL varying by +-1 on successive runs.

TOTAL: 2345
PASS:  1735
SKIP:  311
XFAIL: 0
FAIL:  292
XPASS: 0
ERROR: 7

There are some ERRORs worth looking into further but this should be a
useful basis for future work.
