build: fix reasons conflict

The "_disable_reason" variables are subject to naming conflicts.

This has been caught while looking at mingw builds where the graph
application was skipped with an <unknown_reason> (which is caused by a
missing reason variable set in app/graph/meson.build) and the graph
library was skipped with the same <unknown_reason> too, even though
this library meson does set a proper reason variable.

Example in GHA:

=================
Content Skipped
=================

apps:
	dumpcap:	not supported on Windows
	graph:	<unknown reason>
	pdump:	not supported on Windows
...

libs:
	acl:	not supported on Windows
	bbdev:	not supported on Windows
...
	graph:	<unknown reason>
	node:	not supported on Windows

Prefix all those variables with the type of component.
