Add a test of installed library names when name_{suf,pre}fix: is used

Extend platform_fix_name() to handle this case

We avoid using library(version:), so we don't have to teach
platform_fix_name() all the platform details of versioned shared library
naming.  Hopefully that's exercised by platform-specific tests...
