Execute bootstrap in main thread

Browse Source 
Bootstrap in a separate thread was introduced in 746f0b3b7 to workaround
OS/2 small stack size. OS/2 support was discontinued in 2006 and modern
operating systems have default stack size a few times larger than
default thread_stack and it is tunable.

Aim is to reduce usage of LOCK_thread_count and COND_thread_count.
Part of MDEV-15135.
