malloc: Decorate malloc maps
Add anonymous mmap annotations on loader malloc, malloc when it
allocates memory with mmap, and on malloc arena. The /proc/self/maps
will now print:
[anon: glibc: malloc arena]
[anon: glibc: malloc]
[anon: glibc: loader malloc]
On arena allocation, glibc annotates only the read/write mapping.
Checked on x86_64-linux-gnu and aarch64-linux-gnu.
