[ruby/mmtk] Keep track of pending pages in RubyHeapTrigger

We need to keep track of pending pages in RubyHeapTrigger otherwise a large
allocation may cause infinite number of GCs to be ran since it will always
appear that we have enough space in the heap (and thus the heap won't grow)...

Guard against oob read in rb_ary_aref1

When the array is shrunk during rb_arithmetic_sequence_beg_len_step,
ary_subseq_len returns -1. Return an empty array instead of passing the
negative length to ary_make_partial or ary_make_partial_step.

[ruby/fileutils] Skip chown tests when the target group is not assignable

In user-namespace environments (e.g. ChromeOS Crostini) getgroups(2) can report supplementary groups such as the overflow GID 65534 (nobody) that a non-root process cannot actually chgrp a file to. TestFileUtils#setup built @groups straight from [Process.gid] | Process.groups, so the chown tests tried to chgrp to such a group and failed with EPERM instead of being skipped....
