A few more minor tweaks.
* etc/pkgusr/skel-package/build (update_commands): Just use
update-pkg-project.
* etc/pkgusr/handy_funcs (find_pkg_deps): Removed. Wasn't all
that handy.
* etc/pkgusr/handy_funcs (build-update): Copy the new build script
into ${HOME}/build-YYYYmmdd if SXEmacs isn't installed to allow
for manual update.
* usr/bin/forall_direntries_from (IGNORE_READDIR_RACE): For use
primarily in the uninstall script.
* usr/lib/pkgusr/uninstall_package (run): The -ignore_readdir_race
option can't be used here directly. It is now in
forall_direntries_from and activated via env varibable set in this
script.
