Add file list of necessary files of package glib2

Add file list of necessary files of package glib2

Previously, necessary files of glib2 was '*', which means every files in
the rpm package.
But now the package files are downloaded by gbs using BuildRequires, it
is required to specify the required files(because the files of
BuildRequires are all downloaded and mixed so there is no way to specify
which file is from glib2).
Thus, necessary files are added to the glib2-rs.xml.
Additionally, glib2-rs.xml requires file path started with
'/usr/share/gdb/auto-load/usr/lib' and it is architecture-dependent.
To support 64-bit, convert64.sh script is modified to support this.
