Automake installation has two stages:
* `exec` for platform-specific files,
* `data` for platform-agnostic files.

Automake separates the install stages based on the directory (target)
variable name. Built-in targets have known stages. Any custom-defined
ones check simply whether the target name contains `exec` substring.

Currently, the Lua module is installed in the `data` stage, because
`lua` is not considered an `exec` stage name. However, the Lua module
contains C code (it is architecture-specific).

Similar to how Python is installed via `pyexec`, Lua should be
installed via `luaexec`. That way Automake splits it into `exec` stage
correctly.

Internally, the installation target directory is `LUA_INSTALL_CMOD`
which also signals that this is a platform/architecture-specific
installation. This logic remains unchanged, and the Lua `.so` gets
installed to the same target as a result.

This change is also important to allow libtool cleanup to be done in
`install-exec-hook` consistently. Without this change, part of la-files
cleanup would need to be moved to `install-data-hook`.
