S/390: Fix symbolic displacement in lay

Increase the fixup length to 4 for the 20 bit displacement.

gas/ChangeLog:

2018-09-25  Andreas Krebbel  <krebbel@linux.ibm.com>

	* config/tc-s390.c (md_apply_fix): Set fx_size to 4 for 20 bit
	displacements.
	* testsuite/gas/s390/s390.exp: Run new test.
	* testsuite/gas/s390/zarch-z990-symbol-lay.s: New test.
