cmd/go: skip issue33139 when the 'cc' script command is unavailable
With CGO disabled, the test suite tries to run the following and fail:
CGO_ENABLED=0 go test -run=TestScript/link_syso_issue33139 cmd/go
go test proxy running at GOPROXY=http://127.0.0.1:38829/mod
--- FAIL: TestScript (0.01s)

# Test that we can use the external linker with a host syso file that is
# embedded in a package, that is referenced by a Go assembly function.

FAIL: testdata/script/link_syso_issue33139.txt:15:
unexpected error starting command:
fork/exec /dev/null: permission denied
CC was set to /dev/null (during build) in the scenario mentioned above
This patch replaces [!exec:cc] with [!cgo] because we care about the
availability of the 'cc' builtin and not the 'cc' executable in $PATH
