packaging: rpm dependencies: which and file (#6638)

createtmplt.sh will use file, and setup-sysvm-tmplt will use which. this is log:

/usr/share/cloudstack-common/scripts/storage/secondary/setup-sysvm-tmplt: line 74: which: command not found
/usr/share/cloudstack-common/scripts/storage/secondary/createtmplt.sh: line 56: file: command not found
/usr/share/cloudstack-common/scripts/storage/secondary/createtmplt.sh: line 75: file: command not found
/usr/share/cloudstack-common/scripts/storage/secondary/createtmplt.sh: line 42: file: command not found
/usr/share/cloudstack-common/scripts/storage/secondary/setup-sysvm-tmplt: line 74: which: command not found
/usr/share/cloudstack-common/scripts/storage/secondary/createtmplt.sh: line 56: file: command not found

/usr/share/cloudstack-common/scripts/storage/secondary/createtmplt.sh: line 42: file: command not found
when no which and file, systemvm template can not be import correctly(not decompressed, stay bzip2), then libvirtd will report error:

Could not open backing file: Image is not in qcow2 format
Then systemvm can not be started.
