[OE-core] [PATCH 1/3][v2] libevent: fix the multilib header conflict

[Zhixiong Chi]

Error: Transaction check error:
  file /usr/include/event2/event-config.h conflicts between attempted installs of libevent-dev-2.1.8-r0.skylake_64 and lib32-libevent-dev-2.1.8-r0.x86

The conflict is the size macro definition between 32bit and 64bit
such as:
< #define EVENT__SIZEOF_LONG 8
> #define EVENT__SIZEOF_LONG 4
< #define EVENT__SIZEOF_PTHREAD_T 8
> #define EVENT__SIZEOF_PTHREAD_T 4
