ffb0ccd04b Add a BpfMap#clear method.
A caller can mostly already do this via forEach(), but having a
specific method is faster (since the code does not need to read
the value) and easier to use.

The semantics of this method (e.g., ignore ENOENT while deleting
a key, but throw on any other error) match those of the native
BpfMap::clear method.

Test: new unit tests

The two value types are identical so there is no need to have
separate classes for them.
