[kvm-unit-tests PATCH v2] scripts/arch-run.bash: Drop the dependency on "jq"

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

For checking whether a panic event occurred, a simple "grep"
for the related text in the output is enough - it's very unlikely
that the output of QEMU will change. This way we can drop the
dependency on the program "jq" which might not be installed on
some systems.

 v2: Use [[:blank:]]* as suggested by Claudio
