cmd/gomobile: extract import packages more robust

In darwin/arm64, with Xcode13 toolchain, the nm shows a prefix `_` in
the import path, which was previously not handled.

Such as:

000000010009cd70 t _golang.org/x/mobile/app.(*app).Events
000000010009ce70 t _golang.org/x/mobile/app.(*app).Filter
000000010009cdf0 t _golang.org/x/mobile/app.(*app).Publish
000000010009cd80 t _golang.org/x/mobile/app.(*app).Send
000000010009d870 t _golang.org/x/mobile/app.(*app).loop
000000010009d7f0 t _golang.org/x/mobile/app.(*app).loop.func1

This change fixes the regexp for import package extraction and permits
TestRegexImportGolangXPackage to pass.

Go support for Mobile devices

Go Reference

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.


Contributions to Go are appreciated. See https://golang.org/doc/contribute.html.
