linux: use dlopen for libnl3 instead of dynamic linking
Instead of the current behavior of dynamic linking against libnl3 and
libnl-genl-3 when configured with --enable-delayacct, load the shared
libraries on request, if any delay accounting related process field is
active, via dlopen(3), similar to libsensors and libsystemd.
Distribution, who currently build htop with --enable-delayacct, need to
explicitly add libnl3 and libnl-genl-3 as runtime dependencies to
continue supporting delay accounting out-of-the-box.
