Fix install_kustomize.sh so it works on alpine linux

Browse Source 
The install script fails and thinks that alpine linux is in windows. This is because
`$OSTYPE` in alpine linux is linux-musl, not linux-gnu as this script assumes.

I tested these changes with this script:
```

set -euo pipefail

opsys=""
function check {
    opsys=windows
    if [[ "$OSTYPE" == linux* ]]; then
      opsys=linux
    elif [[ "$OSTYPE" == darwin* ]]; then
      opsys=darwin
    fi
}

OSTYPE="linux-gnu"
check
test "$opsys" == "linux" || echo $OSTYPE test failed

OSTYPE="linuxsomething"
check
test "$opsys" == "linux" || echo $OSTYPE test failed

OSTYPE="darwinsomething"
check
test "$opsys" == "darwin" || echo $OSTYPE test failed

OSTYPE="either"
check
test "$opsys" == "windows" || echo $OSTYPE test failed
```
