perf tools: Remove dependency on libaudit

All architectures now support HAVE_SYSCALL_TABLE_SUPPORT, so the flag is
no longer needed. With the removal of the flag, the related
GENERIC_SYSCALL_TABLE can also be removed.

libaudit was only used as a fallback for when HAVE_SYSCALL_TABLE_SUPPORT
was not defined, so libaudit is also no longer needed for any
architecture.
