cpu/vexriscv_smp: Make sbt failures fatal 

When using a non-default VexRiscv cluster config, the netlist for that
config needs to be generated.  This requires sbt to be installed.
If sbt is missing, an error message is printed:

    sh: 1: sbt: not found

This message may easily be lost in the noise, as the build continues, and fails
later with:

    ERROR: Can't open input file `litex/pythondata-cpu-vexriscv-smp/pythondata_cpu_vexriscv_smp/verilog/VexRiscvLitexSmpCluster_Cc1_Iw32Is4096Iy1_Dw32Ds4096Dy1_Ood_Wm.v' for reading: No such file or directory

Make the root cause more visible by raising an OSError, and aborting the
build.
