profstats: Fix whitespace on license notice

This amends commit ebe4c93f2 ("profstats cleanup", 2021-12-01) / #4730.

This is the second paragraph verbatim of one of the GPL license notices
recommended by GNU[1]:

    but WITHOUT ANY WARRANTY; without even the implied warranty of

On all but one (external) file (and on src/profstats/main.c), the notice
uses the same spacing:

    $ git grep -I -F 'FITNESS FOR A PARTICULAR PURPOSE.  See' | wc -l
    156
    $ git grep -I -F 'FITNESS FOR A PARTICULAR PURPOSE. See'
    m4/ax_check_compile_flag.m4:#   MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General
