[PATCH] goarch.bbclass: set SECURITY_CFLAGS for mips64

[<kai.kang@windriver.com>]

From: Kai Kang <kai.kang@windriver.com>

When include conf/distro/include/security_flags.inc, NOPIE flags are
still required for MIPS64 target builds. Otherwise it fails to build
packages such as glide which inherit go.bbclass:

| .../tmp-glibc/work/mips64-wrs-linux/glide/0.13.1-r0/recipe-sysroot-native/usr/bin/mips64-wrs-linux/../../libexec/mips64-wrs-linux/
| gcc/mips64-wrs-linux/7.3.0/ld: .../tmp-glibc/work/mips64-wrs-linux/glide/0.13.1-r0/go-tmp/go-link-518447869/go.o:
| relocation R_MIPS_26 against `a local symbol' can not be used when making a shared object; recompile with -fPIC`
