Add support for using time64 on big-endian machines.
For BE architectures there is one significant difference
in comparison with time64 support for little-endian
architectures like ARMv7.
The difference is that we strictly need to pass two 64bit
values to system calls because Linux Kernel internally uses
`struct __kernel_timespec` and similar, which consists of two
64bit fields.
For this reason many files have been changed to convert
pointers to timespec-family structures (mixed of 64bit and 32bit values)
to the pointer of the similar but 64bit-only structures
for using as system calls args.
This is general prerequisite for any BE architecture.
