    scripts/gdb: fix usage of MOD_TEXT not defined when CONFIG_MODULES=n
    
    [ Upstream commit 16501630bdeb107141a0139ddc33f92ab5582c6f ]
    
    MOD_TEXT is only defined if CONFIG_MODULES=y which lead to loading failure
    of the gdb scripts when kernel is built without CONFIG_MODULES=y:
    
    Reading symbols from vmlinux...
    Traceback (most recent call last):
      File "/foo/vmlinux-gdb.py", line 25, in <module>
        import linux.constants
      File "/foo/scripts/gdb/linux/constants.py", line 14, in <module>
        LX_MOD_TEXT = gdb.parse_and_eval("MOD_TEXT")
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    gdb.error: No symbol "MOD_TEXT" in current context.
    
    Add a conditional check on CONFIG_MODULES to fix this error.
