libsys: Don't create or expose __realpathat
Previously, __realpathat was in libc and libsys (as is currently
standard), but not exported from libc which meant the stub in libc was
not filtered and thus libc's copy of the syscall was used. This broke
an upcoming change to CheriBSD limiting syscalls to libsys.
The realpath(3) implementation now uses __sys___realpathat so there are no
consumers of __realpathat. Switch it to PSEUDO (only _foo and __sys_foo
symbols) and remove __realpathat from Symbol.map.
This is a corrected version of 58d43a3cd72a4a85ab8489313672c7eab367495e.
