ubsan: disable UBSAN_ALIGNMENT under COMPILE_TEST
The documentation for UBSAN_ALIGNMENT already mentions that it should not be used on all*config builds (and for efficient-unaligned-access architectures), so just refactor the Kconfig to correctly implement this so randconfigs will stop creating insane images that freak out objtool under CONFIG_UBSAN_TRAP (due to the false positives producing functions that never return, etc).
