[PATCH v2 1/3] mtest2make: cleanup mtest-suites variables

[Paolo Bonzini <pbonzini@redhat.com>]

Remove the "--suite" argument from the .*.mtest-suites variables, and
add it only when actually computing the arguments to "meson test".
This makes it possible to set ninja-cmd-goals from the set of suites,
instead of doing it via many different .ninja-goals.* variables.
