Improve support for the optional ICU dependency.

For GNU make, conditionally populate the `Requires:` field in `re2.pc`.
Use `pkg-config` to obtain the necessary compiler and linker flags when
building `static-testinstall` and `shared-testinstall`.

For CMake, the dependency has to be expressed to CMake itself, not just
to `pkg-config` as above.

Fixes #407.
