[FileDatabase] Optimize addin scanning

The format of the addin cache data is something like below:
Users_therzok_Work_md_monodevelop_main_build_AddIns_MonoDevelop.AzureFunctions_azure-functions-cli-66a932fb_nb_abf27ece.data

That means that the code which is removed was looking for something that would match:
<Full_Path>_sha*.data

Only 1 item matches that, and if the direct query did not exist, it means scanning
the whole folder for another file which matches the pattern is useless.

Reduces AddinDatabase.Update for full VSMac from 1.95s to 0.72s, that's 1.23 spent
just doing IO via Directory.GetFiles.
