tpm2-tools: bump to version 3.1.3

- Drop C++ requirement, which came from tpm2-tss.
- Drop musl restriction.
- Drop the patch to build with LibreSSL, which is not required anymore.
- Update the patch for the "variable may be used uninitialized" error to
  match tpm2-tss 2.1.0, which defines TPM2_ALG_ERROR, not TPM_ALG_ERROR.

-Subject: [PATCH] Fix build with LibreSSL
-
-OPENSSL_VERSION_NUMBER is used to test the version of OpenSSL but this
-test alone breaks the build with LibreSSL due to implicit declarations
-of functions 'RSA_set0_key' and 'HMAC_CTX_free'.
-
-Test if OpenSSL < 1.1.0 or LIBRESSL_VERSION_NUMBER is defined, instead.
