Colin Cross 6c6e6cd64d Don't hide *.kotlin_module in turbine dependencies
The jars containing the merged header classes from transitive
static dependencies were stripping all of META-INF/.  Kotlin
puts metadata in META-INF that is used to map the package to
the static class that contains the package-level functions.

This also exposed that the metadata in META-INF is always
called "name.kotlin_module", so a library that contains
kotlin files with a dependency that also contains kotlin files
would shade the metadata file.  Use a unique name instead.

Test: m checkbuild
