filt/remez.c: ensure string format security.
This patch addresses a compilation failure when building EDFbrowser with -Werror=format-security with gcc:
filt/remez.c: In function ‘init_frequencies’:
filt/remez.c:174:27: error: format not a string literal and no format arguments [-Werror=format-security]
174 | fprintf(stderr, spec->err_msg);
| ~~~~^~~~~~~~~
filt/remez.c: In function ‘func_b’:
filt/remez.c:1024:25: error: format not a string literal and no format arguments [-Werror=format-security]
1024 | fprintf(stderr, spec->err_msg);
| ~~~~^~~~~~~~~
The spec->err_msg should be preformatted already, so any occurrence of a percent format control in the resulting string may result in a crash of the function trying to print out the message to stderr. It should be unlikely, but in doubt…
