LOG: [Support] Implement getMainExecutable on Solaris
Many `flang` tests currently `FAIL` on Solaris because the module files
aren't found. I could trace this to `sys::fs::getMainExecutable` not being
implemented.
This patch does this and fixes all affected `flang` tests.
Tested on `amd64-pc-solaris2.11`.
