sysutils/archivemount: Update to 0.9.1

ChangeLog:

* 0.9.1 - Incorporated fixes for compilation problems with newer gcc
          versions. Contributed by Niels de Vos
* 0.9.0 - Make sure the written archive's format is the same or as
          close as possible to the original. Due to a bug written files
          were always in ustar format. Contributed by Jeff Ebert.
        - Add AM_PROG_CC_C_O macro to configure.ac, contributed by
          Jeff Ebert
        - added option -o password, contributed by Scott Worley
        - Pass REG_ENHANCED to regcomp where available (Mac and BSD).
          Otherwise \? has no special meaning. Contributed by Michael
          J. Walsh
        - Removed magic number for block size, it's a constant now.
