build: to verify wide curses, probe for a function that cannot be a macro

This probing has been changed four times in the past:

    git log --grep get_wch

In March 2005, commit 2161fa62 changed the probe from get_wch() to
wget_wch(), reasoning that "get_wch() might be a macro instead of
a function".  (Four months earlier, commit 3ba9c351 changed it
from addwstr() to wget_wch(), probably for the same reason.)  But
three months later, in commit 25799f68, the probe gets changed to
get_wch() again, because "it's a more generic function"...

It seems clear that the non-macro argument is the stronger one.
See the NOTES section in 'man get_wch' for its possible macroness.
