Subject: CONTRIB: make_srpm.sh can prepare SRPM with patches

Creating SRPM with patches is useful for some static analysers, which can do
two builds. The first time without patches and the second with patches.

Bash function add_patches is inspired by file rpm/add_patches.sh from project\
389-ds-base.
