s390-tools doesn't define a common C/C++ standard at the moment.
Set the standard to gnu11/gnu++11, which is also used by the Kernel, and
establish a common baseline for all tools.
The -std flag is added to ALL_CFLAGS and ALL_CXXFLAGS to avoid losing it
in case CFLAGS are set by an outside entity.
It is also added to CLAGS_FOR_BUILD for this one special cross build
case.
The -std flag is removed from all tools that set it manually until now.

`pkg-config` is a well established tool and all of our required
libraries do provide .pc files. Therefore let's declare `pkg-config` as
required and use it. In addition, remove now useless code.

Fixes a bug that make still tried to build pvattest even when the
compilation of pvattest was turned off.
This lead to a build bug when one of the dependencies was not met.
Also fixes the check of the OpenSSL version at build time.
Fixes: 3ab06d77 ("pvattest: Create, perform, and verify attestation measurements")

pvattest is a tool to attest an IBM Secure Execution guest.
In a trusted environment, one can create a request using
`pvattest create`. To get a measurement of an untrusted
IBM Secure Execution guest call 'pvattest perform'.
Again in a trusted environment, call 'pvattest verify'
to verify that the measurement is the expected one.
The tool runs on s390 and x86.
It has the same requirements like libpv and therefore
requires openssl v1.1.1+, glib2.56+, and libcurl.
Additionally, to measure, the linux kernel must provide
the Ultravisor userspace interface `uvdevice` at /dev/uv
and must be executed on an IBM Secure Execution guest on
hardware with Ultravisor attestation support, like IBM z16 or later.
