[OE-core] [PATCH 1/1] perl: fix re-execution of patch/configure

[Paul Eggleton]

The perl recipe's do_configure() does some manual sed replacements over
the entire WORKDIR. Fix the following issues with this:

* Skip patches, which fixes re-execution of do_patch after do_configure
  has run once
* Ensure that the replacement operation does nothing if do_configure is
  re-executed
* Avoid unnecessarily modifying /usr/include paths within documentation
  that will end up being packaged
* Fix a quoting issue in the expression used in the grep command that
  ended up causing files that did not contain .*\.h after /usr/include
  to be matched and modified.

The files modified during do_configure have been compared before and
after this patch to ensure there are no unexpected changes. Some
/usr/include paths that are not within documentation are no longer
being substituted however these are all within comments or scripts for
other Unix operating systems that are not applicable.
