update_repo: extract source files list from *.dsc file

[Totktonada]

Tarantool version: 2.5.0-158-gf84cb1aae.

Now the tool pushes all *.tar.*z files to the storage together with *.dsc: some source files may be missed, some extra files may be pushed.

I would use a snippet like the following to extract exact list of source files (it is from tarantool/tarantool-php#162):

# Push all source files listed in .dsc file together with
# the file.
#
# FIXME: It seems logical to move this logic to the
# packagecloud tool we use.
files="${file}"
if [ "${extension}" = "dsc" ]; then 
     parse_dsc_file='{
         if ($0 == "Files:") {
             FILES_SECTION = 1;
         } else if (FILES_SECTION != 0) {
             print "build/"$3;
         }
     }'
     files="${files} $(awk "${parse_dsc_file}" "${file}")"
fi

Note: It adds build/ before each source file name. Let's adopt it for your needs.

We don't use update_repo.sh anymore. We replaced it with https://github.com/tarantool/rws.
