make abipkgdiff compile with GCC 4.4.7

GCC 4.4.7 won't let us declare an instance of string with __thread.
So for now, package::extracted_packages_parent_dir() juststores its string
globally.  We are single-threaded for now anyway.

	* tools/abipkgdiff.cc (package::extracted_packages_parent_dir):
	The string holding the dir name is no more __thread, as this won't
	compile with GCC 4.4.7
