Add mime type for 'aup3' file extension

The new file extension `.aup3` is not recognized on Linux.

Add a new mime type `application/x-audacity-project+sqlite3` for the
file extension `.aup3` and add this mime type to the supported mime
types of audacity.

Ideally the Audacity team should register two mime types at IATA. These
mime type should probably be named `audio/vnd.audacity.project+sqlite3`
and `audio/vnd.audacity.project+xml`.

Do not strip debug info for CMAKE_BUILD_TYPE=RelWithDebInfo

If `CMAKE_BUILD_TYPE` is set to `RelWithDebInfo` the debug information
should not be stripped. Currently `strip -x` is called when
`RelWithDebInfo` is set. A useless `echo` is called when `Debug` is set.

Skip `strip -x` when `CMAKE_BUILD_TYPE` is set to `Debug` or
`RelWithDebInfo`.

Fix rpath for private libraries on Linux

Installing audacity on Linux will produce private libraries that have
`RUNPATH` set to the build directory instead of the installation
directory.

The root cause is that the library directory is copied to the
installation directory without touching the libraries. The cmake wiki
says in RPATH handling caveats [1]: "Since install-side RPATH tweaking
is an operation that is done by target-specific installation handling,
any target that should have its install RPATH changed (e.g. to
`CMAKE_INSTALL_RPATH`) needs to end up in the installation via an
`install(TARGETS ...)` signature and not via directory-based copying."

So replace `install(DIRECTORY ...)` by individual `install(TARGETS ...)`
for the libraries and modules. Then cmake will replace the `RUNPATH` to
`$ORIGIN/../lib/audacity`, which is still incorrect. Therefore set
`INSTALL_RPATH` explicitly.
