perf dwarf-aux: Fix off-by-one in die_get_varname()
[ Upstream commit 3abfcfd847717d232e36963f31a361747c388fe7 ]
The die_get_varname() returns "(unknown_type)" string if it failed to
find a type for the variable. But it had a space before the opening
parenthesis and it made the closing parenthesis cut off due to the
off-by-one in the string length (14).
