xbps_init() now sets rootdir, cachedir and flags.

That means that the following functions were removed:
	- xbps_set_{cachedir,flags,rootdir}.
	- xbps_get_{cachedir,flags,rootdir}.

With this change fixed an obvious typo that made -c argument to not work,
and now the cache directory is an absolute path not relative to rootdir.
