tools: util-linux: build libuuid

util-linux usually provides libuuid, and is preffered by mtd-utils so lets
enable building libuuid so we can disable it later in e2fsprogs.

Only the static version of library is intentionally built.

+Subject: [PATCH] This re-enables build on macOS.
+
+Weak aliases are not supported by clang on Darwin.
+Instead this fix uses inline asm to make `_uuid_time` and alias to `___uuid_time`
+
+Fixes util-linux/util-linux#2873
