hostapd: fix static build failure

Browse Source 
libnl-3 uses threads and this isn't accounted for in hostapd (or
libnl-3*.pc files for that matter - hostapd doesn't use pkg-config
anyway).
Since linking order matters for static scenarios also throw in -lnl-3
into LIBS first since it gets appended to in hostapd makefiles to add
libnl-3.
