Subject: [PATCH] ci/travis: require "sudo" for ASAN_UBSAN build

Workaround for this fun new issue:

    ==27404==LeakSanitizer has encountered a fatal error.
    ==27404==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1
    ==27404==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
    Failed: E /build|logs :: Runtime errors detected.
