[build] Do not strip away symbols from libraries and executables

By default, scikit-build triggers the stripping of debugging and
other symbols, in order to optimize for space.
However, the stripping is too aggressive on macOS. This has
undesired effects. For example, also the rootcling symbol
`usedToIdentifyRootClingByDlSym` is stripped. Its presence
changes the behaviour of some routines some ROOT libraries, e.g.
when generating dictionaries.
