[PATCH 2/4] meson: bump min XCode CLang to 17.0

["Daniel P. Berrangé" <berrange@redhat.com>]

The current two latest macOS releases (Tahoe and Sequoia) support
XCode 17.x, XCode 26.x and XCode 27.x is in Beta.

XCode 17.x reported CLang 17.0.0, and this continued with XCode 26.0
stream until XCode 26.4 switched to reporting CLang 21.0.0.

A min XCode CLang of 17.0.0 looks appropriate and matches our current
CI job matrix.
