kselftest/runner: allow to properly deliver signals to tests
While running seccomp_bpf, kill_after_ptrace() gets stuck if we run it
via /usr/bin/timeout (that is the default), until the timeout expires.
This is because /usr/bin/timeout is preventing to properly deliver
signals to ptrace'd children (SIGSYS in this case).
This problem can be easily reproduced by running:
$ sudo make TARGETS=seccomp kselftest
...
# [ RUN ] TRACE_syscall.skip_a#
not ok 1 selftests: seccomp: seccomp_bpf # TIMEOUT
The test is hanging at this point until the timeout expires and then it
reports the timeout error.
Prevent this problem by passing --foreground to /usr/bin/timeout,
allowing to properly deliver signals to children processes.
