got: use devel/got-portable to update to v0.95

Bring this package in sync with upstream by relying on its portable
counterpart found at devel/got-portable.

Practically speaking, we're renaming devel/got-portable to devel/got and
making it supersede the former of the two. The previous devel/got
package, an independent port of Game of Trees to NetBSD by @ryoon,
predating the official portable release, gets hereby silently deleted
along with this commit.
