lib/tst_test: Warn on repeated options
The library is not designed in a way that would allow us to pass an
option mutiple times, in such case the last option occurence replaces
all previous ones.
This patch adds a warning in a case that the option pointer is non-NULL,
which means that it has been set at least once already.
