qtchooser: drop useless patch, set PV

* set PV to something better than just 'git'
* drop 0001-Makefile-install-the-man-dir.patch, the change was already applied long before
  the currently used SRCREV, do_patch WARNING: was correctly complaining:

WARNING: qtchooser-git-r0 do_patch:
Some of the context lines in patches were ignored. This can lead to
incorrectly applied patches.
The context lines in the patches can be updated with devtool:

    devtool modify <recipe>
    devtool finish --force-patch-refresh <recipe> <layer_path>

Then the updated patches and the source tree (in devtool's workspace)
should be reviewed to make sure the patches apply in the correct place
and don't introduce duplicate lines (which can, and does happen
when some of the context is ignored). Further information:
