Eneas U de Queiroz c230d7bd7f python3: avoid unnecessary rebuilds 
Move the order in which BuildPackage is called, so that the libpython
package is built ahead of the module packages, to avoid forcing a
clean-build of the package when 'make package/python3/compile' is called
a second time without changes.

The library must be built first, so that when the buildsystem checks for
ABI version changes using libpython3.version, its timestamp should be
older than the dependent package's STAMP_PREPARED file.

define Package/python3/Default/description
Python is an interpreted, interactive, object-oriented programming
language. It incorporates modules, exceptions, dynamic typing, very high
level dynamic data types, and classes. It supports multiple programming
paradigms beyond object-oriented programming, such as procedural and
functional programming. Python combines remarkable power with very clear
syntax. It has interfaces to many system calls and libraries, as well as
to various window systems, and is extensible in C or C++. It is also
usable as an extension language for applications that need a
programmable interface. Finally, Python is portable: it runs on many
Unix variants including Linux and macOS, and on Windows.
