syscall_emul: factor out flag tables into common file
The openFlagTable and mmapFlagTables for emulated Linux platforms are basically identical, but are specified repetitively for every platform. Use a common file that gets included for each platform so that we only have one copy, making them more consistent and simplifying changes (like adding #ifdefs). In the process, made some minor fixes that slipped through due to previous inconsistencies, and added more #ifdefs to try to fix building on alternative hosts.
