enhance(main/util-linux): build libuuid and utils as well

Put library, header and pkgconfig file in libuuid subpackage, which
replaces our standalone libuuid package, and utils in uuid-utils
subpackage.

uuid-utils contains, among other things, uuidgen, which is needed to
be able to compile some packages on device (have forgotten which one(s)
though, has been a few months since I ran into this issue).

Building util-linux with libuuid is also required if we are to enable
other util-linux utilities, like fdisk.
