docs: reflect that delimiter-separated capath is only OpenSSL

curl passes down the capath directly to the backends. OpenSSL will then
delimiter-separate this path internally to support multiple directories
(using its certificate hash scheme). However, the other backends
(wolfSSL, mbedTLS, gnutls) only expect a single directory (and do not
use the hash scheme, preferring to iterate the directory and load all
files). This adjusts the `--capath` documentation to reflect that
multiple paths is an OpenSSL-specific feature. Alternatively, curl could
delimiter-separate these itself, but I'm not sure it's worth it.
