Undefine NAN after including it in Looper.h

Browse Source 
Looper.h needs to include the header for unordered_map, which itself
includes math.h, which defines the macro NAN. Some HALs use enums called
NAN, which causes a build error if the NAN macro is defined. We need to
undef NAN in these cases after including Looper.h.

Test: presubmit: checkbuild

// HACK: NAN is a macro defined in math.h, which can be included in various
// headers. This wifi HAL uses an enum called NAN, which does not compile when
// the macro is defined. Undefine NAN to work around it.
