[LTP] [PATCH 1/1] Add pty07 test for use-after-free in vt_ioctl()

[Cyril Hrubis]

Hi!
Pushed with two minor changes, thanks.

- we do not use inline variable defintion since we are trying to be
  compatible with very old toolchains

- As the test has no CVE assigned the failure message cannot say
  "vunerable"
