syscall.master: Fix comments

Browse Source 
Have more accruate comments. While #if, #else, etc are copied to the
header files, lines that don't start with # are not.  And #include files
are only output to sysinc (which winds up at the front of init_sysent.c
which seems a bit odd). This is all radically undocumented, and likely
has drifted somewhat from 4.4BSD and what other systems do (they've
drifted too, fwiw).
