Subject: [PATCH] Trim whitespace around build tags

This commit trims whitespace around the build tags specified on the
command line in order that invocations such as:

easyjson -build_tags linux

generate the correct "// +build linux" rather than adding additional
whitespace to give  "// +build  linux".
