package/util-linux: optionally add libpthread to uuid.pc

Buildroot commit 31af509b4f bumped
util-linux from version 2.40.2 to 2.41.1.

Upstream release 2.40.3 contains
e143539d30
which unconditionally adds -lpthread to uuid.pc causing build errors for
other packages using non-threaded toolchains like erofs-utils.

Fixes:
