[PATCH] builddeb: fix errors caused by objtree redefinition

["Darrick J. Wong" <darrick.wong@oracle.com>]

In commit 7e1c04779efd51154baf652e653ceb24ce68939b ("kbuild: Use
relative path for $(objtree)"), objtree was redefined from whatever
$(CURDIR) is to a simple ".".  Unfortunately, this breaks builddeb,
which was relying on $objtree to be an absolute path, not a relative
one.  Since the script is run from the object directory, pick up a
more absolute value for objtree where it's needed.
