packaging: remove hg-ssh.8.html from Inno installer We don't ship hg-ssh because it requires a python.exe to run, which we don't ship. So it doesn't make sense to ship the HTML documentation for this tool. This change makes the Inno install layout more consistent with WiX, which doesn't ship this file. Functionality for removing files has been made generic, in anticipation of future expansion. Differential Revision: https://phab.mercurial-scm.org/D7169
