[OE-core] [PATCHv3 2/4] lib/oe/utils: Add function format_pkg_list()

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

The class PkgsList returns a dictionary with all the installed
packages, because the data structure is a dictionary there is
needed to format the data in order to write to a file.

The function format_pkg_list returns a formated sting with all
packages installed. The output will depend on the requested format
when calling the function.
