xfree86/config: Kludge around const strings

Browse Source 
defaultFontPath is now a const char * so that it can be initialized
from a string constant. This patch kludges around that by inserting
suitable casts to eliminate warnings. Fixing this 'correctly' would
involve inserting some new variables and conditionals to use them.
