[PATCH] target/xtensa: fix meson.build rule for xtensa cores

[Max Filippov]

import_core.sh tries to change Makefile.objs when importing new xtensa
core, but that file no longer exists. Rewrite meson.build rule to pick
up all source files that match core-*.c pattern and drop commands that
change Makefile.objs.
