[PATCH] Add support for building extra packages

["Grant Likely" <grant.likely@arm.com>]

The build.sh script is very useful for setting up the build environment
before calling the package build. Sometimes additional packages are
needed when building the SCT. (e.g., it is useful to build ShellPkg).
Refactor the build code to allow additional DSCs to be added to the
build.
