mythplugins configure disables mythbrowser

[dwilga@…]

The configure script for mythbrowser looks for khtml_part.h in two places, but fails to look for just "khtml_part.h" by itself, so it wasn't finding where Mandrake installs the file, in /usr/include. This patch fixes the problem.

(In [7574]) Closes #495.

Check for khtml_part.h in more places, also synced has_library() to the one in mythtv/configure.
