e4088913b5 Separate constructing the path to the policy away from systrace_addpolicy() and

4e11de6548 Further correct handling of `inpath'. 
The path in the policy is not normalized, and shouldn't be. We accept
only an absolute path, possibly with one trailing slash. Make note of
that in the manpage.

1b7133edad From marius@openbsd: 
Fix an issue when scripts are executed under systrace where the argv[0]
would be normalized, and hence break scripts that depend on how they were
called.

If a string considered a filename is too long, don't exit but just let the
syscall fail, it might not actually be a filename.

0e3af04f6a use native syscallnames[] array for 'aout' and 'aoutm68k' "emulations" - it's 
only used for syscall name <-> number translations, and the native array
is guaranteed to be superset of the former 'aout' and 'aoutm68k' arrays

this re-adds 'aoutm68k' support, and replaces change made in 1.14

g/c #include's which are no longer needed (including aout_syscalls.c), and
also add some comments for the emulations[] array
