.gitignore: support building on Windows

These items are already listed, albeit without `.exe` suffix.
Presumably, this is because BusyBox-w32 is traditionally cross-compiled
on Linux.

However, we are about to introduce a CI build definition that builds
BusyBox-w32 in MSYS2 (using mingw-w64-gcc), meaning that those
executables might very well exist _with_ `.exe` suffix.

Let's ignore those, too.
