Subject: [PATCH] Fix warnings when compiling under clang

Introduced by #4849 (add wait for processes by name)

../src/builtin_wait.cpp:23:14: warning: using the result of an assignment as a condition without parentheses [-Wparentheses]
    while (j = jobs.next()) {
           ~~^~~~~~~~~~~~~
../src/builtin_wait.cpp:23:14: note: place parentheses around the assignment to silence this warning
    while (j = jobs.next()) {
             ^
           (              )
../src/builtin_wait.cpp:23:14: note: use '==' to turn this assignment into an equality comparison
    while (j = jobs.next()) {
             ^
             ==
