tools/util-linux: fix libuuid linking

The pkgconfig file that autotools uses is wrong for static libraries.
meson does the right thing but for static libraries, .private entries
need to move to non .private.

Fixes compilation with at least mtd-utils.

+Subject: [PATCH] move libpthread to Libs
+
+OpewWrt uses static host libraries and as such dependant libraries must
+be moved to public Libs. meson handles this automatically but Autotools
+does not.
