subrepo: avoid sanitizing ".hg/hgrc" in meta data area for non-hg subrepos

Before this patch, sanitizing ".hg/hgrc" scans directories and files
also in meta data area for non-hg subrepos: under ".svn" for
Subversion subrepo, for example.

This may cause not only performance impact (especially in large scale
subrepos) but also unexpected removing meta data files.

This patch avoids sanitizing ".hg/hgrc" in meta data area for non-hg
subrepos.

This patch stops checking "ignore" target at the first
(case-insensitive) appearance of it, because continuation of scanning
is meaningless in almost all cases.
