Merge branch 'eyraud/test_256' into 'master'

Do not use gpr_common_args in xcov_suite_args

See merge request eng/das/cov/gnatcoverage!725

gpr_common_args passes the -v switch when the testsuite is run in
qualification mode, which results in passing `-v` to every gnatcov
invocation, yielding regressions.
