Decorate BSS mappings with [anon: glibc: .bss <file>], for example [anon: glibc: .bss /lib/libc.so.6]. The string ".bss" is already used by bionic so use the same, but add the filename as well. If the name would be longer than what the kernel allows, drop the directory part of the path. Refactor glibc.mem.decorate_maps check to a separate function and use it to avoid assembling a name, which would not be used later.
