runtime_loader: Detect and trigger on PE binaries

* Previously PE binaries would trigger the "incorrectly executable" dialog. Now we get a special message for B_LEGACY_EXECUTABLE and B_UNKNOWN_EXECUTABLE * Legacy at the moment is a R3 x86 PE binary. This could be extended to gcc2 binaries someday far, far, down the road though * The check for legacy is based on a PE flag I see set on every R3 binary (that isn't set on dos ones) * Unknown is something we know *is* an executable, but can't do anything with (such as an MSDOS or Windows application) * No performance drops as we do the PE scan last * Tested on x86 and x86_gcc2
