[LTP] [PATCH 2/2 v2] epoll_pwait: Add test variants for epoll_pwait2 in epoll_pwait01

[Cyril Hrubis]

Hi!
Pushed with minor changes, thanks.

* Move the check_epoll_support() to the setup to abort the test early if
  syscall is not supported

* Revoved the .min_kver since we check for the syscall availability now

* Reformatted the description a bit so that it renders nicely in
  metadata
