tools: tpm2_listpersistent add friendly attr output

Rather than just dumping raw hex for object attribute output,
output the human readable names.

Output this:
persistent-handle[0]:0x81000000 key-alg:rsa hash-alg:sha256 object-attr:fixedtpm|fixedparent|sensitivedataorigin|adminwithpolicy|restricted|decrypt

versus:
persistent-handle[0]:0x81000000 key-alg:rsa hash-alg:sha256 object-attr:0x300b2
