timer.h: add mono_time_diff_microseconds()

The current way to get a simple mono_time difference is:
    1. Declare a rela_time struct
    2. Assign it the value of mono_time_diff(t1, t2)
    3. Get microseconds from it using rela_time_in_microseconds().

This patch adds a simpler method. Now one only needs to call
    mono_time_diff_microseconds(t1, t2) to obtain the same value which
    is produced from the above three steps.
