Remove redundant stat/lstat calls from glob

Glob was calling IsSymlink and IsDir on each visited directory entry,
which resulted in an lstat and then a stat call on each.

Instead, use lstat when not following symlinks and use stat when
following symlinks, then use the result to check if the entry is a
directory.

Test: glob_test.go
