expand: Eat closing brace for length parameter expansion
When we are doing VSLENGTH expansion, the closing brace is currently
not removed in evalvar. This causes the caller argstr to terminate
prematurely as it would interpret the closing brace as one that
belongs to a parameter expansion at the outer level.
This patch fixes it.
