[S390] fix s390x_newuname
The uname system call for 64 bit compares current->personality without masking the upper 16 bits. If e.g. READ_IMPLIES_EXEC is set the result of a uname system call will always be s390x even if the process uses the s390 personality. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
