Allow remove wget

wget is not included with base Cygwin, so I see no reason why it cannot be
removed. Worst case it can be reinstalled using setup-x86_64.exe

Also

- removed some quotes where they were not needed
- replaced a statement piping to Bash with more appropriate xargs statement

apt-cyg
