To use tpm2-tools like tpm2_pcrread on the system image should be installed
additional software. Without adding libtss packages to the RDEPENDS attempt to
run with tss2-tcti fails like:

ERROR:tcti:../tpm2-tss-3.0.3/src/tss2-tcti/tcti-swtpm.c:592:
Tss2_Tcti_Swtpm_Init() Cannot connect to swtpm TPM socket
