misc: Update the valgrind suppression file

When needs to prefix the event with Memcheck now.
convert: Convert carriage returns to newlines in comments

Pharo started to use only a carriage return in class comments,
re-add the SyntaxConverter and replace the cr with a nl. This
is not the best place to do (as it impacts all conversions) but
it is not clear where one could at it.

	* scripts/Convert.st: Replace \r with \n in class comments.
kernel: Make gst-sunit -p package.xml work for resources

Currently testing a package that will execute code like this

	(PackageLoader packageAt: #MyPackage) / 'test.file'

will not be able to load 'test.file' unless the package has
already been installed. Add a method to the PackageLoader
extension to register the package so the lookup will return
the right package.

	* kernel/DirPackage.st: Add PackageLoader>>#insertPackage:
	PackageDirectories>>#addFirst: and DirPackageGroup.
	* scripts/Test.st: Use PackageLoader>>#insertPackage:
