perf syscalltbl: Remove syscall_table.h

The definition of "static const char *const syscalltbl[] = {" is done
in a generated syscalls_32.h or syscalls_64.h that is architecture
dependent. In order to include the appropriate file a syscall_table.h
is found via the perf include path and it includes the syscalls_32.h
or syscalls_64.h as appropriate.

To support having multiple syscall tables, one for 32-bit and one for
64-bit, or for different architectures, an include path cannot be
used. Remove syscall_table.h because of this and inline what it does
into syscalltbl.c.

For architectures without a syscall_table.h this will cause a failure
to include either syscalls_32.h or syscalls_64.h rather than a failure
to include syscall_table.h. For architectures that only included one
or other, the behavior matches BITS_PER_LONG as previously done on
architectures supporting both syscalls_32.h and syscalls_64.h.
