[Build] Add a space character to seperate the url and hash value

[xumia]

Why I did it

[Build] Add a space character to seperate the url and hash value for Azure Storage SAS Key
If it contains high privilege info, it will be skipped.

How I did it

It only has impact on url packages, does not have impact on the other packages, such as git, deb.
If the url is azure blob storage and contains SAS key, check the privilege and the format.
For checking the privilege part, it makes sure it only contains read or list permission only, if other permissions, skip the url.
For the SAS format, if the SAS ends with '&sp=r' or '&sp=rl', then additional space character will be added in the end of the url, when using the url, the additional character will be removed.
