RFR : 8206255 : fix compiler/intrinsics/sha/cli/TestUseSHAOptionOnSupportedCPU.java jtreg test on linux s390x

[Baesken, Matthias]

Hello  , could you please review this small  fix  for SHA handling on  s390x.
It  does  the same we have already  on  aarch64  and  x86(-64)   -   in case of  all 3 flags   UseSHA1Intrinsics, UseSHA256Intrinsics, UseSHA512Intrinsics   set to false  we
 Set also  UseSHA to false .

The test   compiler/intrinsics/sha/cli/TestUseSHAOptionOnSupportedCPU.java    revealed  the difference on s390x .
The test  outputs :

java.lang.AssertionError: Option 'UseSHA' is expected to have 'false' value
'UseSHA' option should be disabled when all UseSHA*Intrinsics are disabled
