[PATCH libgpiod v3 2/4] tools: tests: use "$@" instead of $*

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

$@ does not break up quoted arguments which is what we want in all cases
in the bash test-suite. Use it instead of $*. While at it: prevent
globbing with double quotes but allow variable expansion.
