stm32mp: stm32prog: fix the last character of dfu_alt_add third parameter

The third parameter of dfu_alt_add(), the string description of alternate,
is build in stm32prog_alt_add() with a unnecessary character ';' at the
end of the string.

This separator was required in the first implementation of
dfu_alt_add() but is no more needed in the current implementation;
this separator is managed only in dfu_config_interfaces() which call
dfu_alt_add() for this parameter without this separator.

And since the commit b6e3be8f1c86 ("DFU: Check the number of arguments
and argument string strictly"), this added character cause an error when
the stm32prog command is executed because the third parameter of
dfu_alt_add() must be a string with a numerical value; 's' must be NULL
in the result of call in dfu_fill_entity_mmc():
  third_arg = simple_strtoul(argv[2], &s, 0);

Fixes: b6e3be8f1c86 ("DFU: Check the number of arguments and argument string strictly")
