scripts/build/binary: disable pkcs11 on static builds with CGO_ENABLED=1

[thaJeztah]

• follow-up to scripts/build: make sure osusergo is set for static with CGO enabled #3490
• static check is failing, similar to [master] static-linux: verify that binaries are static docker-ce-packaging#430
• possibly can be fixed through / similar to changes in Switch to GitHub Actions docker-credential-helpers#209

pkcs11 cannot be compiled statically if CGO is enabled (and glibc is used)
see

cli/vendor/github.com/miekg/pkcs11/pkcs11.go

Line 75 in 3897c3f

c->handle = dlopen(module, RTLD_LAZY);

see #3490 (comment)

When trying to do otherwise, warnings are printed (and shouldn't be ignored,
similar to the osusergo build-tag):

Still need to look into this one. Reproduction steps;

docker run -it --rm golang:1.19.5-bullseye

go env CGO_ENABLED
1

git clone https://github.com/docker/cli /go/src/github.com/docker/cli
cd /go/src/github.com/docker/cli
git checkout v23.0.0
DISABLE_WARN_OUTSIDE_CONTAINER=1 make binary

Notice the warnings in the output;

Note that the binary is statically linked though;
