Kernel: Remove unnecessary StringBuilder from sys$create_thread()

Browse source 
A series of refactors changed Threads to always have a name, and to
store their name as a KString. Before the refactors a StringBuilder was
used to format the default thread name for a non-main thread, but it is
since unused. Remove it and the AK/String related header includes from
the thread syscall implementation file.
