Those directories were located in /etc/acmed/, which is not the best
choice. According to the Filesystem Hierarchy Standard, they should be
located in /var/lib/acmed/.
Because systems may have different conventions, those values are now
configuration at build time.

The part of code that are specific to OpenSSL are now included only if
the openssl feature is activated. The generic parts of code included in
OpenSSL specific files has been moved out.
Currently, OpenSSL does not have the required
`EVP_PKEY_get1_ED(25519|448)` functions, hence EdDSA has been partially
implemented and disabled. Once OpenSSL 3.0.0 is out and the `openssl`
crates implements the bindings to those functions, full EdDSA
implementation could be done and activated.
Conditional compilation has been implemented using `rustc-cfg`
instructions rather than features so it can be activated from the build
script depending on whether or not the cryptographic library supports
Ed25519 and Ed448.
