[Darwin, testsuite] Update tests for common section use.

These two tests are explicitly testing the use of specific
sections or assembler directives for data that is placed in
common.  Append -fcommon to the flags to restore them.

gcc/testsuite/ChangeLog:

2019-11-21  Iain Sandoe  <iain@sandoe.co.uk>

	* gcc.dg/darwin-comm.c: Add -fcommon to compile flags.
	* gcc.dg/darwin-sections.c: Likewise.
