ca-certificates: fix on-target postinstall script

When the package is installed directly on the machine (instead of
installing it in the rootfs directly), the postinstall script fails with
the following error:

/usr/sbin/update-ca-certificates: line 75: shift: shift count out of range

The reason is that the "update-ca-certificates" script is executed with
the "--sysroot" argument, and as the sysroot $D is passed. However on the
target system this variable doesn't exist, so the argument is passed without
this mandatory value, and the execution fails.

To avoid this error, check if the $D variable exists, and pass the --sysroot
argument only when it does.
