Anhad Singh 1c5668acd4 feat(dso): do not zero memory 
The region is mapped with the `MAP_ANONYMOUS` and thus already
initialised with zeros.

According to POSIX Issue 8:

> Anonymous memory objects shall be initialized to all bits zero.

Anhad Singh bbc86d8027 fix(libc): use ld.so's allocator 
Previously, this was implemented incorrectly because `tcb.mspace` was
set just *before* jumping to the program's entry point. However,
`alloc_init` is called when the init functions are run for `libc.so`, so
`tcb.mspace` must be initialized *before* the init functions are
run.

Anhad Singh 64d3793190 fix(ld_so): page faulting when library not found 
The error handling was already in place. The reason it was page faulting
is that, on failure, the function exits as soon as it encounters an
`Err` variant. When that happens, the DSO object for which the
dependency was being loaded is dropped. Dropping it calls `munmap` to
unload the executable and also runs the functions in `.fini`. However,
`run_fini` should only be called if the `DSO` is being unloaded after it
has been successfully loaded (i.e. all dependencies were satisfied and
all init functions had run).

Closes #1599
