Subject: [PATCH] install: fix disable via unit file path

Drop the check for unit file name validity. install_info_add does that
anyway. Also pass NULL in place of name argument to install_info_add if
we are dealing with path to a unit file. install_info_add will figure
out a name from a path and it will correctly populate
UnitFileInstallInfo with both name and path. Then in
unit_file_search called from install_info_traverse we can take a
shortcut and attempt to load unit file directly.
