cmd/link: work around dsymutils not cleaning temp file
Some versions of dsymutils, notably the one in clang 14.0.3, which
is shipped in some versions of Xcode, have a bug that it creates a
temporary directory but doesn't clean it up at exit. The temporary
directory is created in DSYMUTIL_REPRODUCER_PATH (if set,
otherwise TMPDIR). Work around the issue by setting
DSYMUTIL_REPRODUCER_PATH to the linker's temporary directory, so
the linker will clean it up at exit anyway.
Fixes #59026.
