gn2bp: Remove srcs from out/test

cc_library_static modules that build proto cc files directly specify
with //out/test path. But these files are generated by other genrule
modules and should be specified by the genrule name.
So, this commit removing files with //out/test path from the srcs.

Test: ./update_result.sh
