[bug#29413] Add inputs for pcmanfm and a CVE-2017-8934 patch

[brendan.tildesley@openmailbox.org]

[-- Attachment #1: Type: text/plain, Size: 191 bytes --]

I found that there is a CVE patch for pcmanfm in Arch, so I added it after my inputs patch. I don't know what the code does or if it's needed so only add it if you can judge it is reasonable.

Subject: [PATCH 1/2] gnu: pcmanfm: Add missing inputs. Remove comment.

* gnu/packages/lxde.scm
[inputs]: Add gvfs, for trash and mounting support.
[propagated-inputs]: Add lxmenu-data, for "Open With..." Applications list.
Remove comment suggesting to use --sysconfdir. Inspection of the configure
  script shows that <output>/etc is used for configuration by default anyway,
  so such a flag is not needed.
