Not that I know of. All of the clients facts are submitted as params
in the initial request for a catalog. There's no client <=> server
feedback loop during catalog compilation.

Yes. That seems like the canonical way to do it.

Does it? I thought if you used pluginsync you had those facts
available when you requested the actual catalog. Should take just a
moment to test. Oh, you may be able to use subscribe/notify params to
signal Service[puppet] when your target package is installed. That
would force an immediate reload and run, giving you your fact for
sure.
Is this "3rd party" software installed/managed in the same puppet
catalog as your File[foo.comf]? If so you could get clever with
manifest evaluation order and try to inspect the already defined
Package:
class foo {
include foo::application
include foo::config
}
class foo::config {
require(foo::package)
if defined(Package[foo-x86_64]) or ($foo_fact == 'x86_64') {
$foo_path = "lib64"
} elsif defined(Package[foo-i686]) or ($foo_fact == 'i686'){
$foo_path = "lib"
} else {
fail("Could not detect a version of Package[foo]. This is
bad.")
}
}
This is probably too clever by half though. And using defined() is
morally wrong 95% of the time. And I'm not positive that the require
will force the manifest eval order in your favor. But if it gets the
job done....
