ISLC: Fix hash

[linsui]

Fix #2397

But I bump into another error

Installing 'islc' (1.0.1.2) [64bit]
ISLC%20v1.0.1.2.exe (338.8 KB) [===================================================================] 100%
Checking hash of ISLC%20v1.0.1.2.exe ... ok.

Relpace extract_dir with installer works well

    "installer": {
        "script": [
            "Move-Item \"$dir\\ISLC v$version\\*\" \"$dir\"",
            "Remove-Item \"$dir\\ISLC v$version\" -Recurse -Force"
        ]
    }

Maybe it caused by the space in extract_dir.
