optee: fix format string for printing optee build_id

There has been a recent change in OP-TEE to print 8 and 16 character
commit id for 32bit and 64bit architecture respectively.
In case if commit id is starting with 0 like 04d1c612ec7beaede073b8c
it is printing revision as below removing leading 0
"optee: revision 4.4 (4d1c612ec7beaed)"
