oe-git-proxy: Allow explicit IP addresses in $NO_PROXY
Without this fix, if one specified, e.g., 127.0.0.1 in $NO_PROXY, the
oe-git-proxy script would fail with a message like this:
/home/pkj/yocto/poky/scripts/oe-git-proxy: line 64: 32-127.0.0.1: syntax error: invalid arithmetic operator (error token is ".0.0.1")
