rust: kbuild: emit dep-info into $(depfile) directly
commit e174dd14bf0beac811a5201e370ab26ce8c67f23 upstream.
After commit 295d8398c67e ("kbuild: specify output names separately for
each emission type from rustc"), the preferred pattern is to ask rustc to
emit dependency information into $(depfile) directly, and after commit
2185242faddd ("kbuild: remove sed commands after rustc rules"), the
post-processing to remove comments is no longer necessary as fixdep can
handle comments directly. Thus, emit dep-info into $(depfile) directly and
remove the mv and sed invocation.
This fixes the issue where a non-ignored .d file is emitted during
compilation and removed shortly afterwards.
[ Like Gary mentioned in Zulip, this likely happened due to rebasing
the builds part of the old `syn` work I had. - Miguel ]
