strace.1.in: display -k option description only if it is enabled

Browse Source 
Leverage the fact that manpage is generated and add condition statements
around mentions of -k option.

* strace.1.in (.SH SYNOPSIS): Put option list inside an
".if '@ENABLE_STACKTRACE_TRUE@'#' .ig end_unwind_opt ... .end_unwind_opt"
condition; add a second list of options without -k and put it inside
".if '@ENABLE_STACKTRACE_FALSE@'#' .ig end_no_unwind_opt ... .end_no_unwind_opt"
condition.
(.SS Output format) <-k>: Put it inside
".if '@ENABLE_STACKTRACE_TRUE@'#' .ig end_unwind ... .end_unwind"
condition, remove the mention of --enable-stacktrace configuration
option requirement.
