Install directories mode 755 instead of using umask
Problem reported by Antoine Amarilli in:
https://lists.gnu.org/archive/html/automake/2019-01/msg00000.html
and followed up by Akim Demaille in:
https://lists.gnu.org/archive/html/bug-bison/2020-07/msg00040.html
* bin/automake.in: Add a comment about this.
* lib/install-sh: Ignore umask; just create directories mode 755
unless overridden via -m (for non-intermediate directories only).
Also, fix 'umask=$mkdir_umask' typo.
* lib/mkinstalldirs: Likewise.
