Subject: Using fork of metastore to work when getpwuid isn't usable

After testing the built of Metastore on a server, I noticed that because
its `/etc/passwd' doesn't have the list of users, the `getpwuid' call
within metastore failed and wouldn't let it finish.

So I looked into the code and was able to implement a solution to this
problem by adding two options to it for default values for the user and
group. Also, file attributes are not necessary in our (current) use case of
metastore and caused crashes on our server, so they are also disabled.
