autoconf: update curses.m4

Replace the obsolete AC_TRY_COMPILE with AC_COMPILE_IFELSE/AC_LANG_PROGRAM
in the curses check for the getmaxyx macro.

This change was done manually instead of using autoupdate because the
program prologue argument for this particular check is an m4 macro,
which will not expand to code when autoupdate adds m4 quotes to the
AC_LANG_PROGRAM arguments.
