Migrate the libuuid detection to use pkg-config via PKG_CHECK_MODULES. This allows for better portability on systems where library paths may differ from standard locations. To align with pkg-config standards (which typically provide include paths ending in .../uuid), the source code includes are updated from <uuid/uuid.h> to <uuid.h>. A fallback mechanism using AC_CHECK_LIB is retained for environments without pkg-config, ensuring backward compatibility. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@gmail.com>
