It fixes two issues:

1) Current implementation extracts package name from URL and gets
 it along with percent-encoding which leads to following error:
    | DEBUG: Executing shell function rootfs_install_pkgs_isar_download
    | Starting pkgProblemResolver with broken count: 0
    | Starting 2 pkgProblemResolver with broken count: 0
    | Done
    | E: Unable to locate package libstdc%2b%2b-12-dev
    | E: Unable to locate package g%2b%2b-12
    | E: Unable to locate package g%2b%2b

 To fix it the second field (extracted by sed) will be used as
 deb file name.

2) In case of cross compile the arch of package is lost. F.e. the
 gcc-14-base_14.2.0-19_arm64.deb will be transformed in
 gcc-14-base name and amd64 version will be downloaded instead of
 arm64.

 With this fix the specified version of deb package will be
 downloaded as the URL is used for download.

While implementing my patch, I noticed this dependency as well. I now
have a simpler solution which just uses cp. Once it passes the fast CI,
I'll send it.
