[LTP] [PATCH] unshare01: add EINVAL check

[Petr Vorel]

Hi lufei,

Please next time have a look on other tests, if the same thing is already
being tested or not.  EINVAL is already tested in unshare02.c (as -1).

That's why is this patch not needed (if really high value should be tested,
which I don't think so, it should be in unshare02.c).

Also, we try to not mixing positive tests (e.g. CLONE_FILES) with negative ones
(e.g. EINVAL), we put negative to separate test.

nit: "eno" is not much descriptive, we usually use exp_errno.

Kind regards,
