scripts/gdb: add lx-symbols command

This is probably the most useful helper when debugging kernel modules:
lx-symbols first reloads vmlinux.  Then it searches recursively for *.ko
files in the specified paths and the current directory.  Finally it walks
the kernel's module list, issuing the necessary add-symbol-file command
for each loaded module so that gdb knows which module symbol corresponds
to which address.  It also looks up variable sections (bss, data, rodata)
and appends their address to the add-symbole-file command line.  This
allows to access global module variables just like any other variable.
