[kvm-unit-tests PATCH 2/2] s390x: Fix is_pv check in run script

[Nicholas Piggin <npiggin@gmail.com>]

Shellcheck reports "is_pv references arguments, but none are ever
passed." and suggests "use is_pv "$@" if function's $1 should mean
script's $1."

The is_pv test does not evaluate to true for .pv.bin file names, only
for _PV suffix test names. The arch_cmd_s390x() function appends
.pv.bin to the file name AND _PV to the test name, so this does not
affect run_tests.sh runs, but it might prevent PV tests from being
run directly with the s390x-run command.
