vhaudiquet d14d8c07bd build: move the entitlements next to the Homebrew formula
All consumers live in packaging already: the formula codesigns at
install, and the CI and release workflows codesign the built binary.
The macOS dir held nothing else.

# The formula lives in the repo and ships through the
# vhaudiquet/homebrew-ecrou tap; it needs the same tap libkrun's
# krunkit comes from, because the engine is dlopen'd from those kegs
# at runtime.

<<~EOS
The binary is ad-hoc signed with the com.apple.security.hypervisor
entitlement. Rebuilding from source (cargo) requires re-signing:
codesign --force --sign - --entitlements packaging/homebrew/ecrou.entitlements target/release/ecrou
`ecrou probe` reports this when the entitlement is missing.
