[LTP] [PATCH] msgrcv03: make explicit kernel config requirement

[Po-Hsu Lin]

With commit eeed458492cc ("lib/tst_kconfig: Validate variables"), the
kernel config check is now more strict.

In this msgrcv03 test, it will fail on an ARM64 system running with
Ubuntu Bionic 4.15 kernel:
  tag=msgrcv03 stime=1605780268
  cmdline=msgrcv03
  contacts=
  analysis=exit
  <<<test_output>>>
  CONFIG_CHECKPOINT_RESTORE
                           ^
  Missing value

  tst_kconfig.c:475: TBROK: Invalid kconfig variables!

While the kernel config shows:
  $ grep CONFIG_CHECKPOINT_RESTORE /boot/config-4.15.0-1087-aws
  CONFIG_CHECKPOINT_RESTORE=y

Change the kernel config requirement to CONFIG_CHECKPOINT_RESTORE=y
to solve this issue.
