libeigen: Remove LGPL code

Since libeigen is a header-only library, LGPL effectively has the same
properties as GPL when it comes to affecting the licensing of the code
that uses libeigen. To avoid the problem, backport a patch to remove all
LGPL-2.1 code from the library.

Switch to using "Minpack" rather than "MINPACK" as license since the
former is the official SPDX name.

Also correct the licenses for ${PN}, ${PN}-dbg and ${PN}-dev to reflect
that they do not contain any GPL code (the GPL code is only used for
benchmark tests and does not affect what is installed).

License-Update: Correct the license information
