package/gnutls: disable tpm2-tss

Disable tpm2-tss to avoid the following circular dependency if
BR2_PACKAGE_TPM2_TSS_FAPI is selected:
tpm2-tss -> libcurl -> gnutls -> tmp2-tss
resulting in the following build failure of libcurl or rtmpdump since
commit caff4179a4481233257f5f475ca57ce9061af900:

configure: error: TLS not detected, you will not be able to use HTTPS, FTPS, NTLM and more.
Use --with-openssl, --with-gnutls, --with-wolfssl, --with-mbedtls, --with-schannel, --with-secure-transport, --with-amissl, --with-bearssl or --with-rustls to address this.

[...]
