auto/otel: Remove pkg-config check

@thresheek reported an issue trying to configure OTEL support on Amazon
Linux 2

  checking for OTEL requirements:
    - checking for rust compiler ... found
    - checking for cargo ... found
    - checking for OpenSSL library ... found
  Package openssl was not found in the pkg-config search path.
  Perhaps you should add the directory containing `openssl.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'openssl' found

We successfully built the test program with '-lssl -lcrypto', but then
tried to use 'pkg-config openssl --cflags --libs' to override
NXT_OTEL_LIBS.

On Amazon Linux2 there is no openssl.pc, they have a openssl11.pc.

Let's just remove the pkg-config check, if we get here, we have
successfully built with '-lssl -lcrypto', so just go with that (it also
matches what we do in auto/ssltls).
