[PATCH libgpiod 4/4] tools: tests: remove dependency on grep

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

We only use grep in one place where we can use the -regex option of find
instead. Switch to using find --regex and drop grep entirely from the
tools test-suite.
