libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BIT
The reason truncate64 takes 4 args on some arches is that their ABI
requires 64bit values to be aligned on register pair boundaries.
Since this alignment affects more than just truncate64, rename the
define to properly document its purpose. This also allows us to
expand it to the other impacted syscalls (which will be done in a
follow up commit).
