fix obsolete uses of AC_MSG_NOTICE

[Bruno Haible]

Hi,

In the configure output of a full gnulib testdir, we have thousands of
"checking ..." messages but also 2 times "configure: checking ..."

...
checking whether fflush works on input streams... (cached) no
checking for _fseeki64... no
checking whether fstatat (..., 0) works... yes
checking for sys/mount.h... yes
configure: checking how to get file system space usage
checking for statvfs function (SVR4)... yes
checking whether to use statvfs64... no
checking for two-argument statfs with statfs.f_frsize member... yes
checking dustat.h usability... no
checking dustat.h presence... no
checking for dustat.h... no
checking sys/fs/s5param.h usability... no
checking sys/fs/s5param.h presence... no
checking for sys/fs/s5param.h... no
checking sys/filsys.h usability... no
checking sys/filsys.h presence... no
checking for sys/filsys.h... no
checking sys/statfs.h usability... yes
checking sys/statfs.h presence... yes
checking for sys/statfs.h... yes
checking for statfs that truncates block counts... no
checking for ftello... (cached) yes
checking whether ftello works... (cached) yes
checking for struct statfs.f_type... yes
checking whether __func__ is available... yes
checking whether futimens works... needs runtime check
checking for mmap... (cached) yes
checking for MAP_ANONYMOUS... yes
checking for mmap... (cached) yes
checking for MAP_ANONYMOUS... yes
configure: checking how to do getaddrinfo, freeaddrinfo and getnameinfo
checking for library containing getaddrinfo... none required
checking for getaddrinfo... yes
...

I propose to remove the 'configure: ' prefix in these two lines.

        Simplify "configure: checking ..." messages.
        * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Use AC_MSG_CHECKING instead of
        AC_MSG_NOTICE.
        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Likewise.
