[Toybox] [PATCH] bufgetgrgid: fix for very large groups.

[enh]

In theory, both getpwuid_r and getgrgid_r need to loop until the buffer
is large enough. In practice, that's true for me with getgrgid_r. Even
though the old hard-coded pw buffer size was enough for me, I've fixed
that too on the assumption that there's someone out there that needs
the general code.
