Mock FileInfo.Delete does not consider MockFileData.AllowedFileShare property

[eobeda]

Describe the bug
Mock FileInfo.Delete does not consider the MockFileData.AllowedFileShare property during the delete operation. Similar to #747, but on the FileInfo interface.

To Reproduce
The following test reproduces the error:

 [Test]
 public void MockFileInfo_Delete_ShouldThrowIfFileAccessShareHasNoWriteOrDeleteAccess()
 {
 // Arrange
 var fileSystem = new MockFileSystem(new Dictionary<string, MockFileData>(StringComparer.OrdinalIgnoreCase)
 {
 { @"c:\bar\foo.txt", new MockFileData("some demo content") { AllowedFileShare = System.IO.FileShare.None } },
 { @"c:\bar\baz.txt", new MockFileData("some demo content") { AllowedFileShare = System.IO.FileShare.None } },
 });

 // Throws exception, as expected
 Assert.Throws(typeof(System.IO.IOException), () => fileSystem.File.Delete(@"c:\bar\baz.txt"));

 var fi = fileSystem.FileInfo.FromFileName(@"c:\bar\foo.txt");

 // Does not throw exception, but should
 Assert.Throws(typeof(System.IO.IOException), () => fi.Delete());
 }

Expected behavior
As the AllowedFileShare is set to NONE, an exception should be throw when the delete is attempted.

Thanks!

Thanks for reporting!

It should be mentioned that Linux filesystems do not honor the FileShare flag at all.
