The "-s -w" flags in GO_PKG_LDFLAGS tells the Go compiler to strip the
binaries it produces. Since the default Go package build process will
strip binaries when CONFIG_USE_STRIP or CONFIG_USE_SSTRIP are selected,
these flags are unnecessary.

When CONFIG_NO_STRIP is selected, these flags override the user's
intention of building unstripped packages.

This removes these flags for all relevant packages.

Add GO111MODULE=auto to GO_PKG_BUILD_VARS to allow the package to be
built in non-module mode.

Module-aware mode will be mandatory in the next golang release.
