linux: readahead: convert to SYSCALL_ALIGN_64BIT
The readahead syscall has the 64bit register align issue for all arches. Only mips was handling this though. Clean up the common readahead.c to use the SYSCALL_ALIGN_64BIT define so that we can throw away the mips version and make this work correctly on arm/ppc/xtensa.
