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.

This fixes a following compiling issue:
| agent.c:33:19: fatal error: error.h: No such file or directory
|  #include "error.h"

it's back-ported from lttng-tools upstream, we need it in SRC_URI
since 2.8 is still the latest release.

The lttng-modules are being pulled by the tools-profile image feature,
however, not every kernel has the CONFIG_TRACEPOINTS feature enabled.

This change makes the build do not fail when CONFIG_TRACEPOINTS is not
available, allowing it to be kept being pulled by default.

For thoese recipes that are inheriting python*-dir.bbclass, there is
already a PYTHON_SITEPACKAGES_DIR present, use that definition replacing
redundant "${libdir}/python*/site-packages".
