vdso.7: Fix parisc gateway page description 

The parisc gateway page currently only exports 3 functions:
The lws_entry for CAS operations (at 0xb0), the set_thread_pointer
function for usage in glibc (at 0xe0) and the Linux syscall entry
(at 0x100).

All other symbols in the manpage are internal labels and
shouldn't be used directly by userspace or glibc, so drop them
from the man page documentation.
