Better parsing of team name in /bin/top

[jonas.kirilla]

When running for example 'cat /dev/urandom' /bin/top shows 'urandom' as the team name. ProcessController shows '/bin/cat /dev/urandom'.

I think team_info.args usually starts with "/" as far as I can tell, but it can also start with "./". The path of the executable may contain spaces and there may be arguments following it. Tricky to parse I suppose. What's done in src/bin/top.c looks a bit naive though:

if (get_team_info(t.team, &tm) < B_NO_ERROR) {
    strcpy(tm.args, "(unknown)");
} else {
    if (p = strrchr(tm.args, '/')) {
        strcpy(tm.args, p + 1);
    }
}

"The function strrchr() returns a pointer to the last occurrence of ch in str, or NULL if no match is found." (​http://www.cppreference.com/stdstring/strrchr.html)

Perhaps the team_info struct could be improved in R2.

Moving to R2 as it needs an API change (of struct team_info).
