modules: Make .module_license read-only

Browse Source 
Currently .module_license is set writable, that is, the section has the
SHF_WRITE flag set, in the module's ELF headers. This probably never
actually matters but it can't possibly be correct. The patch sets that
data as "const" which causes that flag not to be set.
