gpu: nvgpu: unit: libnvgpu-fifo for tmake makefiles

channel and tsg units used to build object files from
upper fifo directory. But this was causing build
dependencies issues and stale .o files could be used.
Fixed this by building a shared library for nvgpu-fifo
for tmake makefiles.

Jira NVGPU-3480
