Android can only run c-shared libraries which means that every
Gio program must create its window and event loop from an init
function.
The same applies to iOS but for a more benign reason: the gio tool
builds programs in c-archive mode for iOS and links the binary with
a Objective-C driver.
Allow Gio programs to run off its main function by linking to and
invoking main even from Android libraries and iOS ditto.

Before this change `go list <pkg>` was used to sanitize the import
path of the package argument. That doesn't work well for building
Go source files directly:
gio -target android helloworld.go
where `go list helloworld.go` simply returns "command-line-arguments".
A better way is to leave the package path alone, and compute the
output file separately from the import path, as reported by
`go list -f {{.ImportPath}} <pkg>`.
