Fix broken OpenSSL version check for IPv6 proxy in check_proxy() (#3095)

Browse Source 
check_proxy() gated IPv6 proxy support on a home-grown version check
${OSSL_VER_MAJOR$}${OSSL_VER_MINOR} -ge 11 at two places, which had a
stray "$" causing a "bad substitution" error. On non-LibreSSL builds
this aborted the rest of check_proxy() for any IPv6 proxy (literal
[addr]:port, or a hostname resolving only to AAAA), so PROXY was never
rebuilt into a valid "-proxy ..." argument and downstream openssl calls
failed with an error mentioning neither IPv6 nor the proxy.

Beyond the typo, the concatenation approach was itself unsound:
OSSL_VER_MINOR carries the patch component (e.g. "1.1" for OpenSSL
1.1.1), so ${OSSL_VER_MAJOR}${OSSL_VER_MINOR} yields "11.1" and
[[ 11.1 -ge 11 ]] is an arithmetic error. Replace both checks with the
dotted-glob idiom used everywhere else in the file for OpenSSL >= 1.1
gates (e.g. testssl.sh:21441, :8216), which is robust and greppable.
