Check errno on startup in timerfd__{reset_to_very_long,unmodified_errno} #53

Due to a bug in CheriBSD, errno was set non-zero when starting this test, but without these checks the test confusingly failed in the later check which made me think something was wrong in timerfd_create. Check errno on startup to make this more obvious.
