FreeBSD regtest: add FAKE macros for scalar

FreeBSD 15 removed the never-implemented sbrk syscall.
Arm64 also has a few missing syscalls (backward compat ones
that predate the arm64 port). Rather than having an ever
increasing number of expecteds the aim is to use these
FAKE macros. It's a bit fiddly to get the matching text.
