Commit 2b6a3f061f11 ("mm: declare VMA flags by bit") added a number of
overrides to the rust bindings helper as the change performed in the commit
caused the rust binder to not be able to automatically determine values of
VMA flags.

However a typo was introduced leaving VM_MAYSHARE to be incorrectly
interpreted as VM_MAYEXEC in rust code. This patch fixes the typo.
