Escape many more special shell characters before calling eval on
an entry to convert a variable to its value. Uncareful writing of
a swtpm-local.conf config file could have lead to files being over-
written using '>' for example.

The signingkey entry can also be a pkcs11: URI. The semilcolons in the URI
have to be escaped due to the shell reading the entries.

GnuTLS can use TPM 1.2 keys for signing. For this we just need to support
key URLs in the GnuTLS format:
tpmkey:uuid=...
tpmkey:file=...
We don't try to read these URLs as files but pass them through as URLs to
the swtpm_cert tool that will then try to sign with the TPM 1.2 key by
passing the URL to GnuTLS API calls.
