app-emulation/dosemu: unbreak misaligned .sys files,  bug #631190

In bug #618366 I've added -no-pie LDFLAGS propagation to 16-bit targets
but did not notice dosemu has different varying base addresses for
different .com files (and I've overlooked 0-based .sys rules).

Specifying wrong base address caused incorrect jump offsets
into the final binary. That caused crash and hangup of cdrom.sys
driver.

This change restores original base addresses.
