Add ORIGINAL_FULLPATH to env

This behaves similarly to REQUEST_URI, but
we need to implement it on our own because
REQUEST_URI is not reliable.

Note that since PATH_INFO does not contain
information about trailing question mark,
this is not 100% accurate, for example
`/foo?` will result in `/foo` in ORIGINAL_FULLPATH
