Revert "fetch: check DISTDIR write access as fetch user (bug 601252)"

This reverts commit 4264ac4b07c4555eb5db2ab21288dba05a7f4b6d.
Dropping privileges for the access call is not useful by itself,
since lock and unlink calls do not drop privileges yet. We might
decide to drop privileges for the entire fetch function call.
