[Buildroot] [PATCH] pkg-cmake.mk: set pkg-config env. vars. in the host configure environment

Cmake may run pkg-config to find the dependencies when configuring a
package. Because of the value of PATH, and it will use the Buildroot's
pkg-config wrapper, which, by default, is configured (via some
environment variables) to find the target dependencies.

So, this change makes sure the pkg-config environment variables are
properly set for finding host dependencies when configuring a
host-package.
