Fix compilation with -disable-inputmethod and -no-inputmethod

As for now here are two sets of inputmethod options:
- -enable-inputmethod/disable-inputmethod - which seems to supposed to
  control whether build the 'inputmethod' module or not
- -inputmethod/-no-inputmethod - which seems to supposed to
  enable/disable inputmethod support without changing the ABI.

Before the patch both -disable-inputmethod and -no-inputmethod were just
breaking the build: -no-inputmethod were disabling some code with
support for the module, but didn't disabled the module build itself nor
build of plugins. -disable-inputmethod were disabling build of plugins
and module, but didn't disabled code depending upon it.

It seems the inputmethod support were still WIP when the last release of
Qt3 came to be, hence the mess.

This patch fixes the build if both -disable-inputmethod AND
-no-inputmethod are supplied. Disabling only one is not enough due to
tqmake/configure have problems handling two different options of the
same name.  Later the -inputmethod/-no-inputmethod should be probably
removed entirely.
