toolchain: fix find failing when directory contains file symlink #125

Seems like I manage to use srclib in unorthodox ways.

Basically I figured why not set $SRCLIBPATH to something like $HOME/.srclib:$GOPATH/src (it as it turns out not a good idea anyway). And one of the packages had a symlink to file which broke toolchain.List

Before fix it would fail with:

lstat /some/something/README.md: not a directory

if README.md was a symlink.

This looks good to me. Thanks for the PR!
