build: fix node build failures in WSL Ubuntu

On WSL systems, `./configure` causes appending of carriage return
(`\r\r`) as leftover and will be appended to the `gyp_args`.
Therefore, it will lead to unhandled exceptions from the `./configure`
execution.
Excluded the empty or whitespace item from the `args` array to
fix the issue.

Fixes: nodejs#41459
