meson.build: install symbolic links instead of compiling multiple times
Currently, among others, the `pipewire-pulse` executable is an
exact copy of the `pipewire` executable. Use meson's
`install_symlink()` to avoid the need for compiling the same thing
multiple times. Also use `custom_target()` so that the aliases
are available in an uninstalled environment.
Do the same for `pw-cat`. The benefit is that all aliases
of `pw-cat` are now available in an uninstalled environment.
This commit increasese the minimum meson version to 0.61.1
as that is needed for `install_symlink()`.
The reason for using 0.61.1 instead of 0.61.0 is the following bug:
