Allow ISOs with UDF filesystems to be uploaded with UploadMediaImage

[rdavisunr]

Is your feature request related to a problem? Please describe.

When attempting to upload an ISO with a UDF filesystem, I received an error that stated: file header didn't match ISO standard

Tracked this error down to the verifyIso function in media.go which subsequently calls verifyHeader, which only allows CD001 in the header (only allowing a ISO with an ISO 9660 filesystem).

Can ISOs with UDF filesystems also be supported?

Describe the solution you'd like

Modify verifyHeader to allow UDF in addition to ISO 9660.

Describe alternatives you've considered

For now, I reverted to creating ISOs in ISO 9660 with Joliet for support of longer filenames.

Hi, @rdavisunr could share such a file for testing?

@vbauzysvmware - sure, ISO is in the attached zip.

For the sake of example, the ISO contains a couple of directories and a binary file (notepad++ installer).

udf-example.zip
