Provide missing .pc files for 10.8

10.8 no longer ships four .pc files which were included in previous
versions, though it does still include the libraries which they pointed
to. This commit provides copies of the .pc files for all of these, and
prepends Library/Homebrew/pkgconfig to PKG_CONFIG_PATH on 10.8.

The .pc files in question are: lib curl, lubexslt, libxml-2.0, libxslt

Fixes Homebrew/homebrew#13673.
Fixes Homebrew/homebrew#13627.
Fixes Homebrew/homebrew#13652.
Fixes Homebrew/homebrew#13482.
Closes Homebrew/homebrew#13572.
