goto: impose scalar context on XSUB return values
GH #24212
In something like
my $ret = an_xsub();
pp_entersub() itself, since 5.001, imposes scalar context if necessary
on the return value(s) from the XSUB: by popping all but the top item in
the return list, or pushing undef if none.
However for this:
sub wrap { goto an_xsub(); }
my $ret = wrap();
pp_goto() hasn't been doing the same, resulting in stack underflow or
the wrong number args returned etc. Somehow no one noticed this for 32
years.
This commit fixes that by more or less copying the XSUB scalar context
fixup code as-is from pp_entersub() to pp_goto().
