Subject: [PATCH] scripts/gdb: fix symbol link when run make cmd out of tree

When running 'make scripts_gdb' command out of kernel source tree, the
symbol links gennerated under build-dir/scripts/gdb/linux is invalid.

$(srctree)/$(src) need to be replaced with $(src) since
commit b1992c3772e6 ("kbuild: use $(src) instead of $(srctree)/$(src)
for source directory")
