subrepo: make "_sanitize()" take absolute path to the root of subrepo

Before this patch, "hg update" doesn't sanitize ".hg/hgrc" in non-hg
subrepos correctly, when "hg update" is executed not at the root of
the parent repository, because "_sanitize()" takes relative path to
the parent repository of subrepo itself and requires that CWD is equal
to the root of the parent repository.

Non-hg subrepo under nested hg-subrepos may cause same problem, too.

This patch makes "_sanitize()" take absolute path to the root of
subrepo to sanitize correctly in such cases.

This patch doesn't normalize the path to hostile files as the one
relative to CWD (or the root of the outer most repository), to fix the
problem in the simple way suitable for "stable".

Normalizing should be done in the future: maybe as a part of the
migration to vfs.
