Remove lib/roken glob()

We no longer use it since removing ftp from appl/.

Note that expansion of ~username/ couldn't have been working because
k_getpwnam() was being called with an unsigned short * that was forcibly
cast to char *, but it really was shorts, not chars...  Anyone who ever
feels like reviving lib/roken/glob.[ch] will want to fix that...
