nimscript: cpFile does not copy executable permissions

[vitreo12]

When running cpFile in nimscript on an executable binary, permissions are not copied over. This makes the copied binary unusable unless chmod +x is run on it afterwards.

Example

test.nims

cpFile(getCurrentDir() & "/someBinary", getCurrentDir() & "/someBinary1")

nim test.nims

Current Output

./someBinary1 is not executable, ./someBinary is. Permissions differ: ./someBinary1 does not have executable permissions. chmod +x ./someBinary1 fixes it.

Expected Output

./someBinary1 should have executable permissions, since ./someBinary had them.

Additionally, I've tried to use the setFilePermissions proc from os.nim, but apparently it is not available for NimScript.
