[PATCH] intel-gpu-tools: remove the --cmd option from gem_seqno_wrap

[tim.gore@intel.com]

From: Tim Gore <tim.gore@intel.com>

gem_seqno_wrap was not being built on Android because it uses
wordexp which is not in Bionic.
After discussion with Mika Kuoppala (the test author) it seems
that wordexp was used to implement the --cmd option that was
really only intended for use during development of the test and
is no longer needed. So I have removed support for this option
and enabled this test for Android.
