b9fb5e1cc8 xbps-uchroot: support read-only bind mounts, misc improvements. 
- Added -B src:dest (like -b) but this makes bind mounts in
  read-only mode.

- Get rid of setfsuid(), it's unnecessary.

- Make sure chrootdir is not '/', use realpath().

- Always set SECBIT_NOROOT, see capabilities(7).

- Do not mount recursively, right now this only mounts
  /dev (ro), /dev/shm (rw), /sys (ro) and /proc (ro).
  Previously any mount below any specific mount were recursively
  mounted in chrootdir.

6ccee8fd5e xbps-uchroot: overlayfs fixes v2. 
- Do not use nftw(3), this won't clean up the tree properly.
  Rather use scandir(3) with alphasort, like xbps-create(1).

- Don't drop privs in the parent to make sure that the
  temp overlayfs tree can be removed properly.

This fixes the issues while building go modules and others
with xbps-src.

Revert "xbps-uchroot: make sure to cleanup tempdir with overlayfs." 
This reverts commit f6a6385b42.

Does not work as expected, and does not fix the real issue
which is still not understood.

xbps-uchroot: stop remounting / unnecessarily. 
The remount is done to use nosuid, but we can get
rid of the remount just because of this specific
option that does not have too much value for our
general usage (xbps-src).

xbps-uchroot: make sure to cleanup tempdir with overlayfs. 
Go modules seem to have too restrictive permissions on
its builddir, making xbps-uchroot(1) unable to remove
its directory tree due to insufficient permissions.

Run nftw() twice, the first run to set chmod 755, and
second run to remove the file.

Fixes `xbps-src -t` with any pkg that uses `build_style=go`.

This should avoid lots of temp dirs in the buildbot
builders while building go modules and others.

5117ff84a2 xbps-uchroot: do not fail if the mount MS_MOVE operation fails. 
This could happen if chrootdir is in a shared mount or when it's not
a real mountpoint. Just continue with chroot().
