[PATCH] selftests: hid: fix vmtests.sh not running make headers

[Benjamin Tissoires]

According to commit 01d6c48a828b ("Documentation: kselftest:
"make headers" is a prerequisite"), running the kselftests requires
to run "make headers" first.

Do that in "vmtest.sh" as well to fix the HID CI.

Looks like the new master branch (v6.5-rc1) broke my CI.

And given that `make headers` is now a requisite to run the kselftests,
also include that command in vmtests.sh.
