Define TRANSPORT_USB in NetworkCapabilitiesUtils temporarily

The new API constant - TRANSPORT_USB didn't in mainline
branch, so the user of TRANSPORT_USB will get build break
when it is built in mainline branch.
Define TRANSPORT_USB in NetworkCapabilitiesUtils temporarily
is a workaround to fix this problem, and it should be removed
once downstream branches are S-based.

(clean cherry-pick)
