Add "_time32" suffixed variants of syscalls to table-syscall-inout.txt

Add "_time32" suffixed variants of syscalls to table-syscall-inout.txt

In addressing a number of y2k38 upstream bugs, some syscalls had a
64-bit time variant added. In doing so, the superseded syscalls were
renamed *_time32.

table-syscall-inout.txt is adapted to consider both variants of these
syscalls.

This change is lifted from

Michael Jeanson.
