[PATCH libgpiod v2 2/3] doc: improve the readability of the prefix variable

[Bartosz Golaszewski <brgl@bgdev.pl>]

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

Currently the default value for prefix - indicating the current
directory - is an empty string. This means that if we do
"{prefix}/foo", we may end up pointing to the root directory which is
not what we want. Make "./" be the default value so that the example
becomes valid and add "/" where we couldn't do it before.
