[Buildroot] [PATCH v1 2/2] package/libwebsockets: fix LWS_MAX_SMP when BR2_TOOLCHAIN_HAS_THREADS is set

[Thomas Devoogdt <thomas@devoogdt.com>]

From: Bart Van Severen <bart.vanseveren@barco.com>

"If LWS_MAX_SMP=1, then there is no code related to pthreads compiled
 in the library. If unset, LWS_MAX_SMP defaults to 32 and a small
 amount of pthread mutex code is built into the library."

This is a misconception, when unset, LWS_MAX_SMP is actually set to 1,
so mutexes aren't built in.

To fix, set it to 32 explicitly when threads are enabled.
