[PATCH v5 04/18] evm, ima: Remove more superfluous parentheses

[Thiago Jung Bauermann]

This patch removes unnecessary parentheses from all EVM and IMA files
not yet cleaned up by the previous patches.

It is separate from the previous one so that it can be easily dropped if
the churn and conflict potential is deemed not worth it.

Confirmed that the patch is correct by comparing the object files from
before and after the patch. They are identical.
