package/linux-pam: separate locale and wchar dependencies

They are currently expressed as such:

     depends on (BR2_ENABLE_LOCALE && BR2_USE_WCHAR)

which is not the common practice in Buildroot. We prefer to use:

     depends on BR2_ENABLE_LOCALE
     depends on BR2_USE_WCHAR

This commit ensures linux-pam is consistent with this best practice.
