abuild: ensure a package has deps before printing them
After the first dep is printed, `shift` is called to avoid the special
case where the first dep cannot have a comma prepended. However,
if there are no deps for a package (seen early on in the aports main
repo in acf-jquery), $# is 0. POSIX specifies that `shift` has two
options when the shift operand (1) is greater than $#:
- if non-interactive, it can exit the shell
- if it does not exit the shell, it must return a non-zero exit code
Since we run the shell with -e, the second case folds in to the first.
BusyBox ash does not implement this behaviour, but bash does when called
as /bin/sh or when the `posix` shopt is set.
