doc: suggest the installation of the libcap development library

All FRR Linux packages are built using libcap-dev (or libcap-devel)
installed in the system. Update the build instructions to suggest
FRR developers to do the same. The main motivation for this is that
the seteuid() system call is too expensive and overall less secure
compared to using the Linux capabilities framework.
