[PATCH] test-container: Install with $(sorted-subdirs) [BZ #24794]

[Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>]

Commit 35e038c1d2ccb3a75395662f9c4f28d85a61444f started to use an
incomplete list of subdirs based on $(all-subdirs) causing
testroot.pristine to miss files from nss.

Tested if the list of files in testroot.pristine remains the same.

2019-07-24  Tulio Magno Quites Machado Filho  <tuliom@linux.ibm.com>

	[BZ #24794]
	* Makeconfig (all-subdirs): Improved source comments.
	* Makefile (testroot.pristine/install.stamp): Pass
	subdirs='$(sorted-subdirs)' to make install.
