[Buildroot] [PATCH next 1/1] package/lsof: change _LICENSE_FILES to use COPYING

[Julien Olivain]

Commit e3322e2c7 "lsof: add license info" added the package license
info. At that time, lsof was at version 4.85. The package was not
including a dedicated license file. Instead, the license text was
copied in many files (source files, readmes, ...). It was then decided
to use the small source file "dialects/linux/dproto.h".

Recently, lsof added a COPYING license file. See [1]. This commit was
first included in lsof version 4.97.0. We can now use this file.

The license file hash is updated due to formatting changes. As a side
note, the copyright year in source file was 1997 (see [2]), whereas in
the new license file it is 2002. Source files have different copyright
dates, and can be as old as 1994, for example in [3]. The rest of the
license text remains unchanged.
