klayout package should set KLAYOUT_PATH

I managed to find one of the issues. $KLAYOUT_PATH was pointing to another klayout installation, and klayout failed to load those plugins. Now, I'm getting the following error (klayout 0.28.3):

ERROR: In freepdk45.lydrc: 'source': Stream has unknown format: sram_bank.gds in Layout::read
ERROR: 'source': Stream has unknown format: sram_bank.gds in Layout::read in Executable::execute

I fixed this issue by setting $KLAYOUT_PATH to miniconda/lib/klayout.

@proppy - I can reproduce the same issue with conda-eda/klayout if $KLAYOUT_PATH is unset.

I realized that klayout searches for plugins in miniconda/lib but the plugins are copied to miniconda/lib/klayout. Is there a reason why you create this directory in build.sh?

mkdir -p ${PREFIX}/lib/klayout/
cp -ar pymod *_plugins ${PREFIX}/lib/klayout/
