tests: fix strace-k.test on alpha

Change strace-k.test to use chdir syscall instead of getpid syscall
because the latter is not universally available, e.g. there is no getpid
syscall on alpha.

* tests/stack-fcall-3.c (f3) <default>: Replace getpid with chdir.
* tests/strace-k.test: Likewise.
* tests/strace-k.expected: Likewise.
* tests/strace-k-demangle.expected: Likewise.
* NEWS: Mention this.
