SUSE-SU-2021:2157-1 Security update for libgcrypt

This update for libgcrypt fixes the following issues: - CVE-2021-33560: Fixed a side-channel against ElGamal encryption, caused by missing exponent blinding bsc1187212...

Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm and the window size is not chosen appropriately. This for example affects use of ElGamal in OpenPGP.
