Fix build fail when add option "-fstack-protector-all"

When using canary check with "-fstack-protector-all" option. It causes a configure
error in systemd-boot when meson.build executes compile simple code to test linker option
"-static-pie" because -nolibstd option prevents using libc. It need for
canary to provide some function as "__stack_chk_guard". So need to turn off
canary check when compile sanity check.
