Subject: [PATCH 2/2] Replace __sched_priority with sched_priority(fixes musl
 build)

The musl C library defines sched_priority, not __sched_priority as GNU
libc and uClibc-ng do. Use sched_priority instead.

This does not break compatibility with GNU libc and uClibc-ng because
both define in sched.h:

  #define sched_priority	  __sched_priority

Fixes the following build errors when building with musl:

  ../src/samples/siprtp.c: In function 'boost_priority':
  ../src/samples/siprtp.c:1137:7: error: 'struct sched_param' has no member named '__sched_priority'
       tp.__sched_priority = max_prio;
         ^

          policy, tp.__sched_priority));
                    ^
