pkg/compiler: fix infinite recursion in template instantiation
Fix a bug found by OSS-Fuzz:
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=17240
We handled the case of infinite recursion in templates
but only if the full type name matches precisely (A -> B -> A).
In this case the name constantly changes due to different
template arguments. Per se this is a not an error
(and we have real cases that use this, e.g. when an nlattr_t
contains nested nlattr_t's), but it's an error if it recurses
infinitely. Restrict recursion on the same template to 10 levels.
