[Buildroot] [PATCH 2/2] support/testing: test_systemd.py: add linux fragment to enable CONFIG_BINFMT_MISC

While investigating [1] one units failed due to missing kernel option
CONFIG_BINFMT_MISC needed by "proc-sys-fs-binfmt_misc.mount" service.

It's because the kernel support autofs4 but not MISC binaries.

Since the systemd test infra use the default defconfig (vexpress),
we need to provide a linux fragment to enable CONFIG_BINFMT_MISC.
