fips: allow to customize provider vendor name

FIPS providers need to specify identifiable names and versions. Allow
to customize the fips provider name prefix, via VERSION.dat which
already allows to customize version & buildinfo. With this patch
in-place it removes the need of patching code to set customized
provider name.

E.g. echo FIPS_VENDOR=ACME >> VERSION.dat, results in

```
$ OPENSSL_CONF=fips-and-base.cnf ../util/wrap.pl ../apps/openssl list -providers --verbose
Providers:
  base
    name: OpenSSL Base Provider
    version: 3.4.0
    status: active
    build info: 3.4.0-dev
    gettable provider parameters:
      name: pointer to a UTF8 encoded string (arbitrary size)
      version: pointer to a UTF8 encoded string (arbitrary size)
      buildinfo: pointer to a UTF8 encoded string (arbitrary size)
      status: integer (arbitrary size)
  fips
    name: ACME FIPS Provider for OpenSSL
