This commit fixes panic occurring if $DENO_DIR is set to a relative path, eg. "DENO_DIR=denodir deno run main.ts". Before creating DenoDir instance given path is checked and if necessary resolved against current working directory. Additional sanity checks were put in place to ensure all caches receive absolute path for the location.
