[PATCH] meson: Use find_program() to resolve the entitlement.sh script

[Philippe Mathieu-Daudé via]

Using ../configure without any particular option generates 31 targets
on Darwin, and meson search for the entitlement.sh script 31 times:

Use find_program() which seems to cache the script path once found.
