treewide: replace homegrown memory_erase with explicit_bzero
explicit_bzero was added in glibc 2.25. Make use of it. explicit_bzero is hardcoded to zero the memory, so string erase now truncates the string, instead of overwriting it with 'x'. This causes a visible difference only in the journalctl case.
