Subject: [PATCH 1/2] Use mutex types compatible with musl (fixes musl build)

PTHREAD_MUTEX_FAST_NP and PTHREAD_MUTEX_RECURSIVE_NP are not defined
in the musl C library. Use values that map to the same mutex type in
GNU libc and uClibc-ng.

Fixes the following build errors when building with musl:

  ../src/pj/os_core_unix.c: In function 'init_mutex':
  ../src/pj/os_core_unix.c:1128:40: error: 'PTHREAD_MUTEX_FAST_NP' undeclared (first use in this function)
    rc = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_FAST_NP);
                                          ^
  ../src/pj/os_core_unix.c:1128:40: note: each undeclared identifier is reported only once for each function it appears in
  ../src/pj/os_core_unix.c:1138:40: error: 'PTHREAD_MUTEX_RECURSIVE_NP' undeclared (first use in this function)
    rc = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE_NP);
                                          ^
