fix(build): test_pipe_block references glm.c, renamed to colibri.c by #391

The #270 rebase resolved the TEST_BINS list but missed the test_pipe_block
rule prerequisite and its #include, both still pointing at glm.c (which #391
renamed to colibri.c) — 'No rule to make target glm.c' broke the Linux C test
suite on dev. Point both at colibri.c. Build-verified locally.
