Make the xrdmapc help text and manpage match the code.

The short option for --list is -l, not -1. The code that defines the
option is src/XrdApps/XrdMapCluster.cc line 481:

      {OPT_TYPE "list",      1, 0, (int)'l'},

$ xrdmapc -1
xrdmapc: Invalid option, '-1'.
$ xrdmapc -l
xrdmapc: '-l' argument missing.

Add a zero-width space (\&) before 'all' at the start of the line, so
that the apostrophe at the start of the line is not interpreted as a
macro.

Fixes rpmlint warning:

$ rpmlint xrootd-client
xrootd-client.x86_64: W: manual-page-warning /usr/share/man/man1/xrdmapc.1.gz 21: warning: macro `all'' not defined
1 packages and 0 specfiles checked; 0 errors, 1 warnings.

Also fixes broken rendering of the man page where the line with the
unknown macro is ignored.

Original:

OPTIONS
       -1 | --list [all|m|s]

       -q | --quiet
            Does not print error messages to cerr; errors appear inline.

Updated:

OPTIONS
       -l | --list [all|m|s]
            'all' lists managers and servers (default), 'm' lists only man‐
            agers and 's' lists only servers.

       -q | --quiet
            Does not print error messages to cerr; errors appear inline.
