psa: Add TF-M utility scripts to python path 

When python3 is enforced to build the ARM_MUSCA_A1 or ARM_MUSCA_B1
targets, it is unable to find binary utility tool scripts which are
imported from TF-M.

The reason to use the python3 environment is as follows: Mbed OS + TFM
contained a faulty boot record TLV, which failed the attestation test
(TF-M regression). The data in the boot record TLV will be included in
the generated attestation token as 1 item in the SW_COMPONENTS claim.

This data (in the boot record TLV) is pre-encoded in CBOR format at
build time and appended to the image during the image signing process
(done by the imgtool Python3 script).
