msi: fix slow start issue on Windows

Until chef/win32-service#85 is merged,
use forked version of win32-service.

This fix should be applied to fluent-package not to block starting
fluentdwinsvc service on Windows.

See fluent#618

Closes: fluent#630

NOTE: even though just putting the following line
does not install forked version of win32-service, so
install it explicitly as same as fluentd gem.
