go: fix building without SECURITY_LDFLAGS

Commit 9985b17a30bb ("go: correctly set debug-prefix-map and build
directory") has changed CGO_LDFLAGS to the manually crafted version of
LDFLAGS to strip out DEBUG_PREFIX_MAP contents.

However this manually crafted version includes ${SECURITY_LDFLAGS}.

If security_flags.inc is not included, the variable is not defined, thus
CGO_LDFLAGS will include the '${SECURITY_LDFLAGS}' literally. When
building the recipe, the build would break with the follwing message:

aarch64-linaro-linux-gcc: error: ${SECURITY_LDFLAGS}: No such file or directory

So, instead of manually specifying variable contents, perform the
expected action: filter offending arguments out of LDFLAGS.
