[LTP] [PATCH] ima_selinux.sh: test2 assumes CONFIG_IMA_DISABLE_HTABLE is configured

[Mimi Zohar]

test2 uses the last "selinux-state" record stored in the IMA measurement
list to determine whether SELinux is in enforcing mode and then compares
it to the selinux enforce file status.

The tst_update_selinux_state flips the SELinux enforce status
(/sys/fs/selinux/enforce) to force a new "selinux-state" record to be
appended to the IMA measurement list.  However, this only happens when
CONFIG_IMA_DISABLE_HTABLE is configured.

Don't fail the test when CONFIG_IMA_DISABLE_HTABLE is not configured.
