Subject: tests: use program_invocation_name
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3c6f9a3bf6fc60dfbbfb043c5735148711f4721b;p=qemu-gpiodev%2Flibgpiod.git

tests: use program_invocation_name

We're using _GNU_SOURCE, so it's ok to use program_invocation_name
instead of storing it manually.
