Previously, the build tools for the FPGA bitfiles would try and autodetect the Vivado executable, but would allow for a `vivado_lab` executable. However, Vivado Lab Edition can't build bitfiles nor run testbenches. Its only use with the USRP FPGA build tooling is to run `viv_jtag_program` and `viv_jtag_list` (which are command-line proxies for probing FPGAs attached to JTAG, and for programming bitfiles over JTAG, e.g. to an X3x0). When Vivado Lab and Vivado were present, it was possible that we ran into issues where Vivado Labs would be preferred, and then builds or testbenches would fail. We therefore remove the ability to use Vivado Lab. Running the Vivado Lab Edition with the GUI, and loading and probing bitfiles is of course still possible, but tools like `rfnoc_image_builder` can no longer accidentally try to use Vivado Lab instead of regular Vivado.
