spirv-tools: improve packaging

spirv-tools is a set of libraries and some binaries that link to those
libraries, so inherit lib_package so that the binaries and the libraries
are packaged separately.

The lesspipe script hasn't needed bash since 2018[1], so remove the bash
dependency and package the script with the other binaries.

The build type unless specified is Debug, explicitly set RelWithDebInfo.
