Infrastructure changes to simplify the conf file.

* Removed the following vars from the conf file: XBPS_BUILDDIR,
  XBPS_PACKAGESDIR and XBPS_SRCDISTDIR. They are always relative
  to XBPS_MASTERDIR and cannot be changed.
* Removed XBPS_INSTALLDIR, it was unused in the code.
* Prepend /tools/bin in PATH for the chroot.
* Don't register a repo in the chroot if the XBPS_PREFER_BINPKG_DEPS
  is not set.
