An update that has seven fixes can now be installed.

## Description:

This update for libgcrypt fixes the following issues:

  * FIPS: Differentiate non-compliant flags in the SLI [bsc#1225939]
  * FIPS: Implement KAT for non-deterministic ECDSA [bsc#1225939]
  * FIPS: Disable setting the library in non-FIPS mode [bsc#1220893]
  * FIPS: Disallow rsa < 2048 [bsc#1225941]
  * Mark RSA operations with keysize < 2048 as non-approved in the SLI
  * FIPS: Service level indicator for libgcrypt [bsc#1225939]
  * FIPS: Consider deprecate sha1 [bsc#1225942]
  * In FIPS 180-5 revision, NIST announced EOL for SHA-1 and will transition at
    the end of 2030. Mark SHA1 as non-approved in SLI.
  * FIPS: Unnecessary RSA KAT Encryption/Decryption [bsc#1225936]
  * cipher: Do not run RSA encryption selftest by default
  * FIPS: Make sure that Libgcrypt makes use of the built-in Jitter RNG for the
    whole length entropy buffer in FIPS mode. [bsc#1220893]
  * FIPS: Set the FSM into error state if Jitter RNG is returning an error code
    to the caller when an health test error occurs when random bytes are
    requested through the jent_read_entropy_safe() function. [bsc#1220895]
  * FIPS: Replace the built-in jitter rng with standalone version
  * Remove the internal jitterentropy copy [bsc#1220896]
