kbuild: Fix removal of the debian/ directory

commit a16c5f99a28c9945165c46da27fff8e6f26f8736 upstream.

scripts/Makefile.clean treats absolute path specially, but
$(objtree)/debian is no longer an absolute path since 7e1c0477 (kbuild:
Use relative path for $(objtree). Work around this by checking if the
path starts with $(objtree)/.

Fixes: 7e1c0477 (kbuild: Use relative path for $(objtree)
