In CI were errors/warnings like:
./scripts/plugins.sh: 7: [: windowsx: unexpected operator
This comparison is compatible with more versions of bash and other
shells and should prevent these messages.
When moving to the new CRT build process, this was missed from the older
build scripts. When building the plugins for Windows, if the files do
not have the `.exe` suffix, boundary fails with errors like the
following:
Error initializing controller: error creating aws host plugin: error fetching host plugin rpc client: exec:
"C:\\Users\\alice\\AppData\\Local\\Temp\\441718622\\boundary-plugin-host-aws": file does not exist
