[PATCH 3/3] build: Add "-d keeprsp" to Ninja flags

[John Snow <jsnow@redhat.com>]

When auditing compilation, it is helpful to be able to see all of the
object files passed during the linking step, which ninja can obscure
behind temporary .rsp "response files". Normally, these are deleted
immediately afterwards - but for debugging purposes, it is helpful to
leave them behind to understand what went wrong.
