[wip] extract distfiles to tmpdir, then move
This was discussed in irc, and it is a very rough and untested draft.

Right now what the patch does is:
 - extract distfiles into a tmpdir
 - later move to XBPS_BUILDDIR, trying to preserve the same semantics of `wrksrc` and `create_wrksrc` as before.

This should not in practice change the current behaviour.

I also included, commented out, one idea of an alternative version of the "move" step with different semantics:
 - if there's a single directory extracted, move that to XBPS_BUILDDIR renaming to $wrksrc
 - otherwise, move the whole tmpdir into XBPS_BUILDDIR with name $wrksrc.

Actually doing the second step would break a lot of builds...
