[LTP] [PATCH v2 2/2] signalfd: Add negative tests

[Cyril Hrubis]

Hi!
Pushed with changes described below, thanks.

- there is no need for three masks we just need one valid mask
  + moved the mask structure into a guarded buffer

- it's pointless to attempt to close the fd_einval2 and fd_ebadf
  as these variables are never assigned a valid fd
