Subject: [PATCH] modules: make .module_license read-only

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.

This patch sets that data as "const", which causes that flag not to be
set.
