Shorten thread names to prevent information loss

The Linux kernel [imposes][1] a 15-byte limit on thread names. This means information that does not fit in this limit, e.g., the pipeline ID of layout and script threads, is lost in a debugger and profiler (see the first column of the table below).

This commit shortens the thread names used in Servo to maximize the amount of information conveyed. It also rectifies some inconsistencies in the names.
