haproxy @1.9.6: error: use of undeclared identifier 'CLOCK_MONOTONIC'

[ryandesign (Ryan Carsten Schmidt)]

​haproxy doesn't build on OS X 10.10:

include/common/time.h:526:2: warning: implicit declaration of function 'clock_gettime' is invalid in C99 [-Wimplicit-function-declaration]
        clock_gettime(CLOCK_MONOTONIC, &ts);
        ^
include/common/time.h:526:16: error: use of undeclared identifier 'CLOCK_MONOTONIC'
        clock_gettime(CLOCK_MONOTONIC, &ts);
                      ^
include/common/time.h:538:16: error: use of undeclared identifier 'CLOCK_THREAD_CPUTIME_ID'
        clock_gettime(CLOCK_THREAD_CPUTIME_ID, &ts);
                      ^

I believe these features were introduced in macOS 10.12.

Using the legacysupport portgroup may help, since it provides compatibility definitions of these things.

haproxy: update to 2.2.1

• remove Makefile patch as change looks to be upstream for this version
• add variant for building with Lua support
• add legacysupport portgroup in an attempt to address: #59355
