Multiple changes to xbps-src and shutils:

* Added XBPS_FETCH_CMD to xbps-src.conf, this will be used to fetch
  distfiles. Please note that it will be copied to the chroot, so
  it should be statically linked or with only libc required.

* Removed libtool_func.sh and associated vars, it's unneeded currently.

* Added keep_empty_dirs, keep_libtool_archives and nostrip. By default
  all empty dirs and libtool archives are removed, and executables and
  libraries stripped, respectively. One can use set the var in a build
  template to change the behaviour.

* Explain in README what are the requirements to build XBPS.
