Subject: [PATCH] trezor: hide behind compile tag

The trezor libraries are not yet stable enough to build
gocryptfs with trezor support by default.

It does not even compile at the moment:

  $ ./build.bash -tags enable_trezor
  # github.com/conejoninja/tesoro/vendor/github.com/trezor/usbhid
  ../../conejoninja/tesoro/vendor/github.com/trezor/usbhid/hid.go:32:11: fatal error: os/threads_posix.c: No such file or directory
    #include "os/threads_posix.c"
           ^~~~~~~~~~~~~~~~~~~~
  compilation terminated.
