configure: Fix detection of ncurses library on Archlinux.

[Sebastian Lackner]

On Archlinux the libncurses library is just an ASCII text file containing "INPUT(-lncursesw)" to force the linker to use libncursesw instead. AC_LINK_IFELSE succeeds, but afterwards, when WINE_CHECK_SONAME tries to figure out the name it fails because it doesn't recognize libncursesw.so as the same library. Using a regexp as pattern is the easiest solution to fix this.

Needs autoreconf.
