[RFC 2/3] scripts/checksyscalls.sh: Make renameat optional

[James Hogan]

The new renameat2 syscall provides all the functionality of renameat
with an additional flags argument, so make renameat optional so that
future architectures can omit it without getting a warning.

This patch doesn't affect existing architectures, so there's no harm for
this to wait for the v3.16 merge window.
