cmake: detect libssh via pkg-config
Also:
- fix broken libssh `pkg-config` behaviour on old Linux.
  (when found, `LIBSSH_LINK_LIBRARIES` remains undefined.)

- delete manual libssh config from Old Linux CI job,
  it's no longer necessary.

Closes #14199

# Note: By default this CMake build script detects the version of some
# dependencies using `check_symbol_exists`. Those checks do not work
# in the case that both CURL and its dependency are included as
# sub-projects in a larger build using `FetchContent`. To support
# that case, additional variables may be defined by the parent
# project, ideally in the "extra" find package redirect file:
# https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package
#
# The following variables are available:
# HAVE_SSL_SET0_WBIO: `SSL_set0_wbio` present in OpenSSL/wolfSSL
# HAVE_OPENSSL_SRP: `SSL_CTX_set_srp_username` present in OpenSSL/wolfSSL
# HAVE_GNUTLS_SRP: `gnutls_srp_verifier` present in GnuTLS
# HAVE_SSL_CTX_SET_QUIC_METHOD: `SSL_CTX_set_quic_method` present in OpenSSL/wolfSSL
# HAVE_QUICHE_CONN_SET_QLOG_FD: `quiche_conn_set_qlog_fd` present in QUICHE
# HAVE_ECH: ECH API checks for OpenSSL, BoringSSL or wolfSSL
#
# For each of the above variables, if the variable is DEFINED (either
# to ON or OFF), the symbol detection will be skipped. If the
# variable is NOT DEFINED, the symbol detection will be performed.
