[roll] Roll fuchsia [ffx][usb] Fixes to vsock function name mismatches

Fixes the peripheral configuration logic to properly recognize the vsock
function name so that it initializes the device correctly when
configured, and fixes the casing on the enum in assembly so that the
name is `vsock_bridge` instead of the more confusing `v_sock_bridge`
when enabling it in assembly.
