installer: Print progress bars and such as soon as \r is read....Fixes <https://issues.guix.gnu.org/59922>.
Previously progress bars and related things would be buffered by
'run-external-command-with-line-hooks' until \n is read.
* gnu/installer/utils.scm (run-external-command-with-line-hooks): Use
'read-delimited' rather than 'get-line'. Pass 'concat as the last
argument.
(%display-line-hook): Remove.
(run-command): Use 'display' instead of '%display-line-hook'.
(%syslog-line-hook): Add "\n" when LINE doesn't end in \n.
(%installer-log-line-hook): Do not add an extra newline.
(installer-log-line): Add an extra newline.
