util-linux: backport patch to skip build of unused objects

util-linux-uuid does not need libtcolors.a and libcommon.a but
they get build regardless. Backport a patch from upstream to
skip them and save some compilation time.

+Description: Automake: use EXTRA_LTLIBRARIES instead of noinst_LTLIBRARIES
+ noinst_LTLIBRARIES causes the libraries to be always built
+ unconditionally. EXTRA_LTLIBRARIES causes them to be built
+ only if other build target needs them.
+ In other words, avoid building libcommon.a and libtcolors.a
+ unless they are needed by another library/executable and
+ save some build time.
