Use system sslcacertfile by default

This patch includes a new functionality to get the sslcacertfile.

With this patch is possible to remove the sslcacertfile variable form the
.offlineimaprc and use the system's default. This could be easy for new users.

With this patch, the user can use ssl without the sslcacertfile option
in .offlineimaprc, use sslcacertfile = <empty> (no include anything
after the equal sign, os specify the sslcacertfile as previosly.

Currently, these are the options:

    User specifies sslacertfile -> OK
    User specifies sslacertfile=OS-DEFAULT
        If the system's default is provided -> OK
        If the system's default is not provided -> Fail
    User do not specifies sslacertfile -> Fail
    User specifies empty sslacertfile -> Fail

With the new option (this patch).

    User specifies sslacertfile -> OK
    User specifies sslacertfile=OS-DEFAULT or
    User do not specifies sslacertfile or
    User specifies empty sslacertfile
        If the system's default is provided -> OK
        If the system's default is not provided -> Fail

Closes #14
