[CMake] Enable -z defs on Solaris
I wondered why I hadn't seen the link failures in D130571
<https://reviews.llvm.org/D130571> on Solaris/sparcv9 and found that
Solaris, unlike Linux, doesn't use `-Wl,-z,defs` when linking shared
objects. The three affected shared objects indeed have undefined
references to several 64-bit atomics.
This patch will expose such issues in the future by defaulting to
`-Wl,-z,defs` on Solaris, as recommended in `ld(1)`.
Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.
