[OE-core] [PATCH] perl: fix re-execution of task

[Venkata ramana gollamudi]

perl package do_configure is changing "/perl-5.14.2/patches/h2ph-multiarch.diff"
 from link to normal file in the process of correcting the paths.
So when patch task is re-executed after complete package building, giving error.

This path correction is not required for links as the link target file
 will be also be modified individually.
Fix done to ignore the path correction during do_configure,
 if file is a link.

[Yocto #2194]
