go 1.24-1.25: build failures against libpact_ffi

[bmomberger-bitovi]

Tested on:

• Win64, Go 1.25.4 (from scoop), libpact_ffi 0.4.16, pact-go 2.0.5,
• Ubuntu 24.04.3 in WSL, Go 1.25.4 (from snap), libpact_ffi 0.4.28, pact-go 2.4.2
• Ubuntu 24.04.3 in WSL, Go 1.24.0 (d/l'ed by apt-get golang-1.23-go package), libpact_ffi 0.4.28, pact-go 2.4.2

When trying to run a test suite using pact-go on Go 1.25, I encounter this error that fails the build and further fails the test:

# github.com/pact-foundation/pact-go/v2/internal/native
cgo: inconsistent definitions for C.pactffi_given_with_param
cgo: inconsistent definitions for C.pactffi_given
FAIL    <containing folder of test files> [build failed]
FAIL

A known-good configuration in the above Ubuntu includes:

• Go 1.23.3 d/l'ed by apt-get golang-1.23-go package),
• pact-go 2.0.5
• libpact_ffi 0.4.28
  When using this config, the tests build and run as expected.

Thanks. Strange, it's working on my Mac. I'll see if we can repro using our build agents, then we have a target to fix.
