misc/cgo/testcarchive: avoid writing to GOROOT in tests Also add a -testwork flag to facilitate debugging the test itself. Three of the tests of this package invoked 'go install -i -buildmode=c-archive' in order to generate an archive as well as multiple C header files. Unfortunately, the behavior of the '-i' flag is inappropriately broad for this use-case: it not only generates the library and header files (as desired), but also attempts to install a number of (unnecessary) archive files for transitive dependencies to GOROOT/pkg/$GOOS_$GOARCH_shared, which may not be writable — for example, if GOROOT is owned by the root user but the test is being run by a non-root user. Instead, for now we generate the header files for transitive dependencies separately by running 'go tool cgo -exportheader'. In the future, we should consider how to improve the ergonomics for generating transitive header files without coupling that to unnecessary library installation.
