Add which/debianutils as runtime dependency for packages

The gp_bash_functions.sh script uses the 'which' command
to locate binaries, but this command may not be available
in minimal system installations, causing runtime failures
when running gpdemo or other utilities.

This commit adds the appropriate runtime dependencies:
- RPM packages: Add 'which' to Requires list
- DEB packages: Add 'debianutils' (provides which command)
  for both Ubuntu 22.04 and 24.04

This ensures the 'which' command is available after package
installation, preventing "command not found" errors during
database initialization and operation.
