security: do not issue warning on existing certificate file during dump

To be able to handle various use cases Anaconda is trying to import
(currently just dump to given location) the certificate both in
initramfs, after switch-root, and early after anaconda start. Therefore
when dumping the certificate to specified file it is difficult to tell
if it overwrites original file existing in the image, so issue just an
info message instead of warning, which should concern only the specific
case of overwriting non-imported file.

Resolves: RHEL-77155
