feat(fence-agents): remove fence-agents-xenapi from metapackage

[christopherco]

Azure Linux targets Hyper-V/KVM, not Xen. Remove fence-agents-xenapi from the fence-agents-all Requires list so it is no longer pulled in by the metapackage. The subpackage is still built but not installed by default.

Verified: build succeeds and fence-agents-all no longer requires fence-agents-xenapi.

Pull request overview

Removes the Xen-specific fence-agents-xenapi dependency from the fence-agents-all metapackage so Azure Linux (Hyper-V/KVM-focused) no longer pulls it in by default, while still building the subpackage.

Changes:

• Add a dedicated fence-agents.comp.toml with an overlay to remove fence-agents-xenapi from the metapackage Requires.
• Remove the now-redundant bare fence-agents entry from components-full.toml.

spec-search-replace is currently unscoped and will replace every occurrence of fence-agents-xenapi in the spec. Repo guidance recommends scoping regex overlays with section and package to limit blast radius (see .github/instructions/comp-toml.instructions.md:119-120). Since this is intended to affect only the fence-agents-all subpackage Requires, please scope it accordingly and ensure the replacement also removes any adjacent separators/line-continuation so we don’t rely on a blank \ continuation remaining in the tag value.
