userdomain: introduce the user certificate file context (was miscfiles: introduce the user certificate file context)

Introduce a new file context for user certificates (user_cert_t)
located in home directories.

Introduce new auxiliary interfaces to read and manage such files
files and directories.

Thanks to Christopher PeBenito for the useful suggestions that
led to this improved version of the patch.

Compared to the previous version, this patch adds the ability to
search the user home directories in the new interfaces.
