Fix vd build error with rpm 4.14 for writing %files debuginfo

Fix vd build error with rpm 4.14 for writing %files debuginfo
This patch is compatible with old writing way in spec file for vd projects.

in some vd project, there is such section:
%file debuginfo
XXXXX
In current logic, there is no need to write this way in rpm 4.14, it will check if
there is XXX.debug kind of files, if there is none, no debuginfo package is generated.
But in vd projects' spec, it put some files which is not XXX.debug files to debuginfo package,
this is not allowed in rpm 4.14.
