build: mark all PE files as wine builtins

This allows libmono to load extra libraries (notably win-iconv) from
system_dllpath.

For example, Fedora's wine-mono is built against a shared win-iconv
installed in system_dllpath, but wine will not search there unless it's
explicitly instructed to do so since wine commit bfbccf1a (ntdll: Prevent
loading Wine system dependencies in place of identically named application
DLLs.).
