package/rpi-firmware: add option to install vcdbg
vcdbg is a tool to help debug the communication with the GPU.
It comes as a binary-only, and in two flavours: one for the hard
floating point ABI, one for the software floating point ABI.
Unfortunately, we have no source code for that tool, only a binary that
was dynamically linked with glibc and libraries from rpi-userland.
So, just install that executable, and let's hope there is no symbol
issue at runtime.
Note: vcdbg needs glibc, threads and !static. Since glibc already
implies threads and !static, we only need to depend on glibc.
