tools/liblockdep: Use realpath for srctree and objtree
If BUILD_SRC or CURDIR contains tailing '/', the file names passed to gcc will contain '//'. It will be contained .o's in debuginfo, then confuse debugedit: https://bugzilla.redhat.com/show_bug.cgi?id=304121 This patch uses realpath command to makesure potential tailing '/'s are removed.
