linux: set CONFIG_ARCH_STRICT_ALIGN=n

Browse Source 
set CONFIG_ARCH_STRICT_ALIGN=n to enable
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS. this
allows loading BPF program with unaligned memory
access generated by clang, see [0].

this change might cause BPF program fail to load
in loongarch CPU models that require strict aligned
memory access.
