tpm2-tss-engine: add .so symmlink to engines package

Without the symlink, the engine is not found by openssl:

openssl engine -t -c tpm2tss
20F0C5BDFFFF0000:error:12800067:DSO support routines:dlfcn_load:could
    not load the shared library:/usr/src/debug/openssl/3.2.4/crypto/dso/dso_dlfcn.c:118:
    filename(/usr/lib/engines-3/tpm2tss.so): /usr/lib/engines-3/tpm2tss.so:
    cannot open shared object file: No such file or directory
...

With sym-link it works (also without extra configuration for openssl)

cd /usr/lib/engines-3/
ln -s libtpm2tss.so tpm2tss.so
openssl engine -t -c tpm2tss
(tpm2tss) TPM2-TSS engine for OpenSSL
    [RSA, RAND]
        [ available ]

For exmample also the Fedora package has the symlink.
