fix(tf-cov-make): add QCBOR path for TC4 build

When building TF-M test suite within TF-A without specifying
QCBOR path, the following build error occurs-

drivers/measured_boot/rse/qcbor.mk:10: *** Error: QCBOR_DIR not set.  Stop.

To resolve this, explicitly set the QCBOR path for hte build that was
failing.

Additonally, provide MEASURED_BOOT=1 to align with the TC3 build
configuration.
