[OE-core] [PATCH] Enable ptest support for lttng.

A majority of the tests will probably fail this way. As of now, most
tests assumes that they are being runned in the build tree and expect
binaries to be at specific paths. We will have to fix this upstream if
you want to integrate our testsuite with ptest.

> ++  -e 's|^not ok \(.*\)|FAIL: \1|' \
> ++  | egrep -h 'PASS|FAIL'

This is sadly needed because we are using TAP as our standardized test
output format across the multiples lttng codebases.

Thanks,
