[PATCH] tests/qtest/migration: Restore include for postcopy

[Fabiano Rosas]

Commit 124a3c58b8 ("tests/qtest/migration: Move ufd_version_check to
utils") moved the ufd_version_check() function to another file but
failed to bring along the <sys/syscall> include, which is necessary to
pull in <asm/unistd.h> for __NR_userfaultd.

Restore the missing include.

While here, remove the ifdef __linux__ that's redundant and fix a
couple of typos.

Fixes: 124a3c58b8 ("tests/qtest/migration: Move ufd_version_check to utils")
