Austin Seipp 77a6b2dd26 scripts/icestorm: use 'yosys-config' to find data directory 
This fixes the icestorm script to query yosys-config itself for the
right data directory. Not only does this fix installs where yosys was
not installed into /usr/local, it also ensures Icarus picks up a data
directory consistent with the version of yosys that you're using.
