docs/scripts/gdb: add necessary make scripts_gdb step
[ Upstream commit 6b219431037bf98c9efd49716aea9b68440477a3 ]
In order to debug the kernel successfully with gdb you need to run
'make scripts_gdb' nowadays.
This was changed with the following commit:
Commit 67274c083438340ad16c ("scripts/gdb: delay generation of gdb
constants.py")
In order to have a complete guide for beginners this remark
should be added to the offial documentation.
