strace.1.in: clarify mpers flags in strace -V output

The previous description was a bit dated.

* strace.1.in (.SH "MULTIPLE PERSONALITY SUPPORT"): Remove "no-m32" and
"no-mx32", describe the situation when some of mpers flags are not
present in strace -V output.

 It is a pity that so much tracing clutter is produced by systems
 employing shared libraries.
