installer: Run commands without hopping through the shell.
* gnu/installer/utils.scm (run-shell-command): Rename to... (run-command): Remove call to 'call-with-temporary-output-file' and hop through Bash. Expect COMMAND to be a list of strings rather than a string. * gnu/installer/final.scm (install-system): Turn INSTALL-COMMAND into a list of strings and pass it to 'run-command'. * gnu/installer/newt/page.scm (edit-file): Likewise.
