package/libtracefs: needs threads

Browse Source 
libtracefs needs threads resulting in the following build failure since
its addition in commit b1dbd3f679:

In file included from /home/autobuild/autobuild/instance-2/output-1/host/xtensa-buildroot-linux-uclibc/sysroot/usr/include/stdio.h:27,
                 from ../src/tracefs-instance.c:10:
/home/autobuild/autobuild/instance-2/output-1/host/xtensa-buildroot-linux-uclibc/sysroot/usr/include/features.h:218:5: warning: #warning requested reentrant code, but thread support was disabled [-Wcpp]
  218 | #   warning requested reentrant code, but thread support was disabled
      |     ^~~~~~~
../src/tracefs-instance.c:20:10: fatal error: pthread.h: No such file or directory
