[PATCH] genericarm64.conf: fix qemu testing with testimage.bbclass

genericarm64 machine has supported qemu for a long time but
the default build config failed with testimage.bbclass to boot
and run oeqa runtime tests.

TESTIMAGEDEPENDS needs qemu utilities so that they are correctly
installed to image sysroot. For qemu machines these are set in
testimage.bbclass but remain unset for non-qemu machines like
genericarm64.

TEST_RUNQEMUPARAMS needs snapshot since default genericarm64 image
is a compressed wic.zst, nographic to run qemu without connected
display which is better on headless build machines, and slirp which
also works on much broader set of build machines than the default
tap networking.

With these set, default genericarm64 core-image-sato boots correctly
with testimage.bbclass and all oeqa runtime tests pass on an x86_64
build machine:

$ bitbake core-image-sato && bitbake -c testimage core-image-sato
...
SUMMARY:
core-image-sato () - Ran 75 tests in 229.248s
core-image-sato - OK - All required tests passed (successes=24,
skipped=51, failures=0, errors=0)
NOTE: Tasks Summary: Attempted 1558 tasks of which 1556 didn't need to
be rerun and all succeeded.

To boot qemu manually:

$ runqemu slirp nographic snapshot core-image-sato
