tmpfiles: Add specifiers to allow running as user instance 

This commit adds specifiers %U, %u and %h for the user UID, name and
home directory, respectively.

[zj: drop untrue copy-pasted comments and move the next text
     to the new "Specifiers" section.
     Now that #7444 has been merged, also drop the specifier functions.]
