[PATCH v4 1/3] format-patch: remove erroneous and condition

Commit 30984ed2e9 (format-patch: support deep threading, 2009-02-19),
introduced the following lines:

	#define THREAD_SHALLOW 1

	[...]

	thread = git_config_bool(var, value) && THREAD_SHALLOW;

Since git_config_bool() returns a bool, the trailing `&& THREAD_SHALLOW`
is a no-op. Remove this erroneous and condition.
