[PATCH v2] kbuild: deb-pkg: apply short -R and -j options

[Dmitrii Bundin]

The long version --rules-file and --jobs are available since 1.18.8
while their short analogues -R and -j have been added since 1.14.7.

The option --rules-file the way it works currently was introduced in the
commit 5cd52673aabdf5eaa58181972119a41041fc85f2 of dpkg dated 23.07.18
with the following changelog entry:

* Fix dpkg-buildpackage option --rules-file parsing. It was trying to parse
  it as --rules-target, which due to the ordering was a no-op.

The current behavior of the long version --rules-file is guaranteed to
be in use starting 1.19.1 and might cause build failures for some
versions newer than 1.18.8 even in spite of being documented that way.
