sockperf: fix musl build (libexecinfo dependency, missing includes)

configure.ac's AC_SEARCH_LIBS([backtrace], [execinfo], ...) fails
with 'libexecinfo not found' on musl, which lacks glibc's
backtrace()/backtrace_symbols(); depend on the libexecinfo compat
library there.
Once configure succeeds, ticks.h's timeval2nsec() needs struct
timeval, which was only pulled in via <sys/time.h> under __FreeBSD__,
and vma-xlio-redirect.cpp calls sscanf()/sprintf() without including
<cstdio>; fix both for musl too.

+Subject: [PATCH] src: fix missing includes for musl (struct timeval,
+ sscanf/sprintf)
+
+ticks.h's timeval2nsec() uses struct timeval, but the header only
+pulled in <sys/time.h> under __FreeBSD__ -- glibc's <time.h> happens
+to declare struct timeval as a side effect of other headers already
+included elsewhere in the build, but musl's does not, so building
+against musl fails:
+
+| ticks.h:115:30: error: member access into incomplete type 'const struct timeval'
+
+Always include <sys/time.h> instead of gating it on __FreeBSD__.
+
+vma-xlio-redirect.cpp uses sscanf()/sprintf() but never includes
+<cstdio>, relying on it being pulled in transitively. That doesn't
+happen on musl either:
+
+| vma-xlio-redirect.cpp:92:14: error: use of undeclared identifier 'sscanf'
+| vma-xlio-redirect.cpp:99:5: error: use of undeclared identifier 'sprintf'
