Fix astro/gpxloggerd build with clang 3.5.0

On arches with 64-bit time_t, astro/gpxloggerd will fail to compile with clang
3.5.0, due to the following -Werror warning:

gpxloggerd.c:199:6: error: absolute value function 'abs' given an argument of
type 'long' but has parameter of type 'int' which may cause truncation of value
[-Werror,-Wabsolute-value]
        if (abs(t - ot) < interval)
            ^
gpxloggerd.c:199:6: note: use function 'labs' instead
        if (abs(t - ot) < interval)
            ^~~
            labs

In this case, replacing the call with labs() is just fine.
