[yocto] [ptest-runner 2/3] Add support to avoid load/run twice a run_ptest script

[Aníbal Limón]

From: Aníbal Limón <anibal.li...@linaro.org>

In some ptest packages exists symlink in the ptest directory causing
to load/run twice the same ptest,

For example in perl5:

/usr/lib/perl -> /usr/lib/perl5
