THRIFT-4797: Go import improvements
This change improves two problems in go code imports:
1. Always rename import the thrift package into "thrift", as we allow
the user to use a different library to replace the official one from
the compiler command line, this makes sure that in compiler generated
go code we can always blindly use "thrift.*".
2. We added auto rename import dedup in d9019fc5a4, but in that change
for system packages we always use the full import path as the dedup
identifier, so system package "database/sql/driver" would not be
detected as a conflict against a thrift go namespace of
"foo.bar.driver". Use the part after the last "/" in system packages
as the dedup identifier instead.
