Remove test_dll from the list of dependencies of common_lib.

test_dll is a test artifact but common_lib is used by our binaries, so this
dependency introduce a dependency between our tools and some test code.

E.g. In order to compile SyzyAsan for x64 you need to also make test_dll.dll
x64 friendly, this doesn't make sense.

This doesn't seem to affect the build, it looks like this dependency wasn't
needed.
