Subject: Platforms/AMD/OverDrive: make capsule support conditional

The signed capsule update support added to the Overdrive platform in
a recent patch inadvertently introduced a dependency on the external
OpenSSL library, which many users may not have installed into their
EDK2 tree by default. So add a DO_CAPSULE variable that defaults to
FALSE, and only build the capsule pieces if it is set to TRUE.
