The regex '-----BEGIN .* PRIVATE KEY.*-----' was matching
'-----BEGIN PGP PRIVATE KEY BLOCK-----' in /etc/ImageMagick-6/mime.xml,
causing a false positive for SSH keys.
Fixed by removing the trailing .* before ----- so the regex now requires
the key header to end directly with -----, which excludes PGP key
definitions that have 'BLOCK-----' at the end.
Tested key types still detected:
- RSA PRIVATE KEY
- EC PRIVATE KEY
- OPENSSH PRIVATE KEY
- DSA PRIVATE KEY
