[libvirt] [PATCH] maint: allow VPATH use of remote_protocol-structs

[Eric Blake]

* src/Makefile.am (remote_protocol-structs): Ensure file lives in srcdir.

Jim's new check didn't quite work in a VPATH setup.

I'm applying it as obvious, since it was a build-breaker:

  GEN    remote_protocol-structs
diff: remote_protocol-structs: No such file or directory
make[3]: *** [remote_protocol-structs] Error 2
