powerpc/vmlinux.lds: Add .text.asan/tsan sections
When KASAN/KCSAN are enabled clang generates .text.asan/tsan sections.
Because they are not mentioned in the linker script warnings are
generated, and when orphan handling is set to error that becomes a build
error, eg:
ld.lld: error: vmlinux.a(init/main.o):(.text.tsan.module_ctor) is
being placed in '.text.tsan.module_ctor' ld.lld: error:
vmlinux.a(init/version.o):(.text.tsan.module_ctor) is being placed in
'.text.tsan.module_ctor'
Fix it by adding the sections to our linker script, similar to the
generic change made in 848378812e40 ("vmlinux.lds.h: Handle clang's
module.{c,d}tor sections").
