[PULL 03/19] device-crash-test: Check if path is actually an executable file

[Thomas Huth <thuth@redhat.com>]

From: Eduardo Habkost <ehabkost@redhat.com>

After the transition to Meson, the build directory now have
subdirectories named "qemu-system-*.p", and device-crash-test
will try to execute them as if they were binaries.  This results
in errors like:

  PermissionError: [Errno 13] Permission denied: './qemu-system-or1k.p'

When generating the default list of binaries to test, check if
the path is actually a file and if it's executable.
