Add a stp file for usage from build directory
For systemtap the location of the process being tapped is crucial, as a
result the existing stp file requires installation for use.
There are now two files:
$(TARGET_DIR)/$(QEMU_PROG).stp-installed: copied to $(tapdir)/$(QEMU_PROG).stp
$(TARGET_DIR)/$(QEMU_PROG).stp: pointing to the built binary, usable
without installation
To use:
stap -I $(TARGET_DIR) ...
