TestVerifyHostname fails (at least on Go 1.26.2/macos 26.4.1)

With Go 1.26.2 and macOS 26.4.1, tls.TestVerifyHostname fails:

$  go test github.com/zmap/zcrypto/tls -run TestVerifyHostname 
--- FAIL: TestVerifyHostname (0.07s)
    tls_test.go:481: x509: failed to load system roots and no roots provided
FAIL
FAIL	github.com/zmap/zcrypto/tls	0.341s
FAIL

I'm not able to repro in a linux docker image of Go 1.26.2, so I suspect that there's some modern macOS specific code needs to be ported over from the stdlib crypto/tls library

Ah, this is the stuff that relies on internal/abi in the Go runtime. Low priority to get this one fixed.
