Allow override_find_program to use an executable.

With this it is now possible to do

foobar = executable('foobar', ...)
meson.override_find_program('foobar', foobar)

Which is convenient for a project like protobuf which produces both a
dependency and a tool. If protobuf is updated to use
override_find_program, it can be used as

protobuf_dep = dependency('protobuf', version : '>=3.3.1',
                          fallback : ['protobuf', 'protobuf_dep'])
protoc_prog = find_program('protoc')
