[LTP] [PATCH v5 1/1] syscalls/mq_open: fix old tests + convert to use new API

[Cyril Hrubis <chrubis@suse.cz>]

Hi!
Pushed with cosmetic changes, removed the now unused enum and fixed a
few over 80 character lines, thanks.

This one is not that bad, but I still prefer the more verbose one.

As far as code readability goes I think that the best solution is to
split the test into two, one for possitive cases and one (or a few more)
for negative ones...
