[build] Allow extra objects to be included in an all-drivers build
The build system allows for additional drivers (or other objects) to
be specified using build targets such as
make bin/intel--realtek.usb
make bin/8086100e--8086100f.mrom
This currently fails if the base target is the "bin/ipxe.*" all-drivers
target, e.g.
make bin/ipxe--acm.usb
Fix the build target parsing logic to allow additional drivers (or
other objects) to be included on top of the base all-drivers target.
This can be used to include USB network card drivers, which are not
yet included by default in the all-drivers build.
