Bug 222872: lang/ruby22: does not build with POSIX-compliant sh -c
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222872

allow both current and POSIX-compliant sh -c

The RB_SET_CONF_VAR macro uses a construct like

sh -c 'command' -- arg0 arg1

and assume that $0 will expand to arg0 and $1 will expand to arg1.

Our current sh implements it that way. However, POSIX specifies that $0 will
expand to -- and $1 will expand to arg0, since the command string is an operand
and not an option-argument. Bug #220587 requests making sh POSIX-compliant in
this regard.

If the argument after the command string does not start with '-', the current
sh behaves as required by POSIX. Therefore, the macros should be adjusted so
this is always the case.

Tested with poudriere, stable/10 with patched head sh.
