Consolidate Linux truncate implementations
This patch consolidates all Linux truncate implementation on
sysdeps/unix/sysv/linux/truncate{64}.c.  It is based on
{INTERNAL,INLINE}_SYSCALL patch [1] to simplify the syscall
construction.

General idea is to build ftruncate iff __OFF_T_MATCHES_OFF64_T is not
defined, otherwise ftruncate64 will be build and ftruncate will be an
alias.  The fallocate will use old compat syscall and pass 32-bit off_t
argument, while fallocate64 will handle the correct off64_t passing using
__ALIGNMENT_ARG and SYSCALL_LL64 macros.

Tested on x86_64, i386, aarch64, and armhf.
