openssl: Fix AWS-LC build

Browse Source 
The `crypt` functions defined here conflict with the `crypt` function
defined in `unistd.h` and trigger compilation errors when building
against the latest version of AWS-LC, which introduced a new transitive
include of `unistd.h` via `bio.h`.

This simply renames the function to avoid the error.

Closes strongswan/strongswan#2786
