x86: shrink __ALIGN and __ALIGN_STR definitions
Impact: cleanup
1) .p2align 4 and .align 16 are the same meaning
(until a.out format for i386 is used which is
not our case for CONFIG_X86_ALIGNMENT_16 anyway)
2) having 15 as max allowed bytes to be skipped
does not make sense on modulo 16

[ small cleanup, use __stringify(), etc. ]
