test: skip mutex Unlock inlining tests on a few builders
Fix builder breakage from CL 148958. This is an inlining test that should be skipped on -N -l. The inlining also doesn't happen on arm and wasm, so skip the test there too. Fixes the noopt builder, the linux-arm builder, and the wasm builder.
