coredump: set ProtectHome to read-only

In https://github.com/systemd/systemd/pull/5283/commits/924453c22599cc246746a0233b2f52a27ade0819
ProtectHome was set to true for systemd-coredump in order to reduce risk, since an attacker could craft a malicious binary in order to compromise systemd-coredump.
At that point the object analysis was done in the main systemd-coredump process.
Because of this systemd-coredump is unable to product symbolicated call-stacks for binaries running under /home ("n/a" is shown instead of function names).

However, later in https://github.com/systemd/systemd/commit/61aea456c12c54f49c4a76259af130e576130ce9 systemd-coredump was changed to do the object analysis in a forked process,
covering those security concerns.

Let's set ProtectHome to read-only so that systemd-coredump produces symbolicated call-stacks for processes running under /home.
