Use IsOriginSecure when checking Web MIDI SYSEX capability.

Use IsOriginSecure when checking Web MIDI SYSEX capability.

Rather than the previous ad hoc check. IsOriginSecure is the standard way.

This CL depends on https://codereview.chromium.org/1049533002/ (Add
IsOriginSecure and GURL::SchemeUsesTLS.) so cannot land before that one lands.
It is a first test-case for the new IsOriginSecure function. PTAL, thanks!

I may replace this check code to somewhere to be consistent with Permissions API
(see https://code.google.com/p/chromium/issues/detail?id=474545), but for now it
LGTM. Defer to content settings owners.

LGTM.

Thanks a lot for this change!
