[Build] Make sure we declare LINUX_STATIC dependencies on Musl.
Everywhere there's a `SWIFT_MODULE_DEPENDS_LINUX Glibc`, there should be
a corresponding `SWIFT_MODULE_DEPENDS_LINUX_STATIC Musl`.
This usually won't bite us, depending on build order and parallelism, but
I hit one of these yesterday so went looking to see if there were any
others.
