QtAutogen: Fix rcc invocation for Qt 5.0 and 5.1 (#15644) 

In commit v3.2.0-rc1~480^2 (QtAutogen: Regenerate qrc files if their
input changes, 2014-09-17) we added use of the rcc `--list` option.
Prior to Qt 5.2 this option was called just `-list`.  Run `rcc --help`
to check for support for `--list` before using it and otherwise fall
back to the `-list` option for compatibility with older versions.
