tu: Fix the advertised maxFragmentInputComponents

This appears to be limited by VPC_CNTL_0::NUMNONPOSVAR, which is an
8-bit bitfield with no possibility for expansion. Also, in practice
we'll be limited by the vertex shader output maximum, which includes
gl_Position, of 128, so that users won't be able to use more than 124
components anyways. Lower it to match the GL blob.
