ZIG_EXE envirnoment variable instead of testing build options

No longer introduce build options for tests. Instead, ZIG_EXE
environment variable is added to any invocation of `zig run` or `zig
test`.

The end result of this branch is the same: there is no longer a
mandatory positional command line argument when invoking zig test
binaries directly.
