powerpc: Use generic fallocate compatibility syscall 



The powerpc fallocate compat syscall handler is identical to the
generic implementation provided by commit 59c10c52 ("riscv:
compat: syscall: Add compat_sys_call_table implementation"), and as
such can be removed in favour of the generic implementation.

A future patch series will replace more architecture-defined syscall
handlers with generic implementations, dependent on introducing generic
implementations that are compatible with powerpc and arm's parameter
reorderings.
