Subject: [PATCH] Fix build error when ntpshm is false

The build fails as follows

libgpsd_core.c: In function 'ntpshm_latch':
libgpsd_core.c:1660:24: error: 'const struct gps_type_t' has no member named 'time_offset'
  || device->device_type->time_offset == NULL)
                        ^
libgpsd_core.c:1663:33: error: 'const struct gps_type_t' has no member named 'time_offset'
  fix_time += device->device_type->time_offset(device);
                                 ^
scons: *** [libgpsd_core.os] Error 1

The solution is to wrap #ifdef NTPSHM_ENABLE around the ntpshm_latch function

Subject: [PATCH] Complete wrapping of ntpshm_latch function in #ifdef
 NTPSHM_ENABLE

Currently, the build fails as follows

gpsmon.o: In function `gpsmon_hook':
gpsmon.c:(.text+0x8b0): undefined reference to `ntpshm_latch'
collect2: error: ld returned 1 exit status
scons: *** [gpsmon] Error 1

Addresses Sacannah bug #43129: ntpshm patch is incomplete.
