Replace PKG_CONFIG variable name with PKG_CONFIG_FILE for the name of
the pkg-config file.
This is preventing a conflict in some build systems where PKG_CONFIG
actually contains the path to the pkg-config executable to use, as the
default assignment in libs.mk is using a weak assignment (?=).
This problem has been found when trying to build the latest version of
Xen tools using buildroot.
Fixes: d400dc5729 ("tools: tweak tools/libs/libs.mk for being able to support libxenctrl")
