[bug#28719] [PATCH 3/6] gnu: qwt: Adjust installation directory layout.

[Hartmut Goebel <h.goebel@crazy-compilers.com>]

From: 宋文武 <iyzsong@member.fsf.org>

* gnu/packages/qt.scm (qwt)[arguments]<#:phases>: Modify 'qwtconfig.pri' to
use a directory layout that matching qtbase.  Modify 'doc/doc.pro' to remove
the misplaced installation of man pages.  Rename phase 'install-documentation'
to 'install-man-pages'.
