cmd/link: set alignment for carrier symbols
For carrier symbols like type.*, currently we don't set its
alignment. Normally it doesn't actually matter as we still align
the inner symbols. But in some cases it does make the symbol table
a bit weird, e.g. on darwin/arm64,
0000000000070000 s _runtime.types
0000000000070001 s _type.*
The address of the symbol _type.* is a bit weird. And the new
darwin linker from Xcode 14 beta doesn't like that (see issue
53372).
This CL aligns them.
Fixes #53372.
