perf script: Find script file relative to exec path
Allow perf script to find a script in the exec path.
Example:
Before:
$ perf record -a -e intel_pt/branch=0/ sleep 0.1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.954 MB perf.data ]
$ perf script intel-pt-events.py 2>&1 | head -3
Error: Couldn't find script `intel-pt-events.py'
See perf script -l for available scripts.
$ perf script -s intel-pt-events.py 2>&1 | head -3
Can't open python script "intel-pt-events.py": No such file or directory
$ perf script ~/libexec/perf-core/scripts/python/intel-pt-events.py 2>&1 | head -3
Error: Couldn't find script `/home/ahunter/libexec/perf-core/scripts/python/intel-pt-events.py'
See perf script -l for available scripts.
$
After:
$ perf script intel-pt-events.py 2>&1 | head -3
Intel PT Power Events and PTWRITE
