[yocto] [patchtest-oe][PATCH] test_python_pylint.py: correct filepath passed to pylint

[changqing.li at windriver.com]

From: Changqing Li <changqing.li at windriver.com>

we cannot get abspath of the added/modified file from info
which is generated by unidiff, we can only get path like:
"scripts/lib/wic/plugins/source/bootimg-biosplusefi.py"

So pylint will responsed as "scripts/lib/wic/plugins/
source/bootimg-biosplusefi.py does not exist"

For modified file:
both pretest and test result have this error, so patchtest
will take as no new error is introduced, so patchtest result
is PASS

For new added file:
since test result have error "... does not exist", and pretest
is empty, so patchtest will FAIL with error "... does not exist"

Fixed by add abspath like ".../openembedded-core/scripts/lib/wic
/plugins/source/bootimg-biosplusefi.py" for the file
