Because it turns out sizeof(time_t) is 8 in 64 bit platforms, but that
results in really broken 'pt' results, where half of the lines are
'invalid date'
Also, endianness handling was swapped in the case of 'pt' and
non-existent in the case of 'rax2 -t' (the latter actually did a weird
hack to swap endianness twice and get valid results).
Now rax2 -t supports the -e parameter to swap endianness.
The usage of r_mem_copyendian with r_print now matches what's done
in other places, with !p->big_endian instead of p->big_endian,
because 0 means swap and 1 means do nothing. Terrible function.
This also fixes some valgrind warnings about uninitialized values
(when copying 4 bytes to a 8 byte time_t)
