Subject: [PATCH 06/12] Call open() rather than open64() in setupdwfl.cxx

open64() is an LFS64 alias that only glibc defines; musl dropped the
LFS64 aliases entirely, so setupdwfl.cxx fails there:

  setupdwfl.cxx:1649:17: error: 'open64' was not declared in this scope

configure.ac already runs AC_SYS_LARGEFILE, so plain open() is the
64-bit one everywhere systemtap builds, and /sys/kernel/notes is a few
hundred bytes in any case.
