libpkgconf: pkg: fix computation of pkgconf_pkg_t.id on Windows. 

Windows allows both \ and / as valid path characters.  A computed path
such as C:\development\libfoo\pkgconfig/foo.pc will result in a computed
pkgconf_pkg_t.id of "pkgconfig/foo".

Accordingly, correct the path normalization for checking for / after
the \ path has been dealt with in all cases.
