name-rev: use strbuf_strip_suffix() in get_rev_name()

Browse source 
get_name_rev() basically open-codes strip_suffix() before adding a
string to a strbuf.

Let's use the strbuf right from the beginning, i.e. add the whole
string to the strbuf and then use strbuf_strip_suffix(), making the
code more idiomatic.
