Use unique names for bulk update commands
A regression introduced in 4c43245e0b (#37700) is causing the `xbps-src update-sys` command to skip the final step of installing the updated packages.

This happens because the `cmd` variable name clashes with a loop variable used in common/environment/setup/install.sh script [line 16](/void-linux/void-packages/blob/4c43245e0b989fa85fe57090a1a584d6e6650546/common/environment/setup/install.sh#L16). Thus the `"$cmd" == installed` comparison ([common/xbps-src/shutils/bulk.sh line 122](/void-linux/void-packages/blob/4c43245e0b989fa85fe57090a1a584d6e6650546/common/xbps-src/shutils/bulk.sh#L122)) fails and the installation step is skipped.

Using unique variable names in `bulk.sh` avoids this problem.
