rcc: Prevent CRLF conversion on Windows for -binary

Fix an issue on Windows where

  rcc -binary project.qrc >project.rcc

resulted in a corrupted file (\n was automatically replaced with \r\n).

This is caused by Qt using fwrite internally, which will automatically
replace linefeed with carriage-return for streams opened in text mode.

The fix forces stdout to binary mode in this case.
