cmd/gomobile: change the working directory to $WORK/src/gobind when go-building

This is a preparation to enable Go modules for gomobile commands.

When Go modules is used, $GOPATH is not available. To build a
local package with Go modules, changing the working directory and
specifying the package by a relative path begining with `./` is
required. Changing the working directory is necessary because
building outside of modules is forbidden.

Specifying $GOPATH is still needed for reverse bindings (i.e.
special packages begining with `Java/` or `ObjC/`). Note that
gomobile with Go modules cannot support reverse bindings so far.

Updates golang/go#27234
