secadm: remove duplicate policies

[uudiin]

There are some duplicate policies in secadm, which are defined in userdom_security_admin_template() and remove them in secadm.

I'm seeing this diff from the GitHub actions:

Allow Rules (0 Added, 2 Removed, 0 Modified)
   Removed Allow Rules: 2
      - allow bootloader_t autofs_t:dir { getattr ioctl lock open read search };
      - allow systemd_logind_t autofs_t:filesystem getattr; [ systemd_logind_get_bootloader ]:True

Dontaudit Rules (0 Added, 1 Removed, 0 Modified)
   Removed Dontaudit Rules: 1
      - dontaudit useradd_t var_spool_t:dir { getattr open search };

But that may be due to other PRs merging. Please rebase so we can verify we don't lose any rules.

@pebenito rebase has been done. As you said, this was due to other PRs merging.
