[PULL 2/8] tests/qemu-iotests: Move the bash and sanitizer checks to meson.build

[Hanna Reitz <hreitz@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

We want to get rid of check-block.sh in the long run, so let's move
the checks for the bash version and sanitizers from check-block.sh
into the meson.build file instead.
