We normally do not need to bother with ifdefs around
specific system-calls. userfaultfd turns out to be
different because our unistd import into linux-headers
is incomplete: it's missing asm-generic bits,
some arm and mips headers.

Fix it up, and drop ifdefs for usefaultfd.

Tested on x86 only.

Pls consider merging this through the migration tree.

  update-linux-headers.sh: add unistd.h
  linux-headers: add asm-generic/unistd.h
  postcopy: drop unnecessary conditions
