sh.1: rm Solaris-specific SHOPT_PFSH info (re: f089d799)

Browse source 
The -P option only ever worked on Solaris so it's questionable it
should have been in the general-purpose manual to begin with. And
now it doesn't even work on Solaris as it disable SHOPT_PFSH with a
patch (that functionality is now provided by a wrapper that works
with all shells). So it's long past time to stop documenting it.

For the same reason, this also removes the info about invoking ksh
as pfksh, etc. -- this is still possible on Solaris with the new
method, but the functionality is no longer actually provided by
ksh. If the Solaris maintainers want it back in the man page, that
should be done by adding a patch to their build system.
