font-util: Fix incorrect PKG_CONFIG_PATH
PKG_CONFIG_PATH always defaults to /usr/lib/pkgconfig, and the host
/usr/lib/pkgconfig is always checked as a fallback; however,
PKG_CONFIG_PATH is currently (incorrectly) set to /usr/lib/pkg-config in
the sysroot, which doesn't exist. On host distros where the font
encoding maps are stored under a different path than OE, this will break
font builds, because ucs2any will attempt to read the sysroot's encoding
maps with the host paths.
