build: only build without libcap on request
Linux FRR builds without libcap are massively slow due to the
signal-based UID/GID synchronization across threads. This disables the
automatic fallback to build without libcap; it can still be requested
with "--disable-capabilities" but if the option isn't given in either
direction and we can't find libcap that's an error now.
