  [lldb][Linux] Parse, but don't store "comm" from /proc/stat file (#100387)

As reported in https://github.com/llvm/llvm-project/issues/89710, the %s
code used for `comm` could and probably does, overflow the buffer.
Likely we haven't seen it cause problems because the following data is
overwritten right afterwards.

Also scanf isn't a great choice here as this `comm` can include many
characters that might trip up %s.

We don't actually use `comm`, so parse but don't store it so we're not
overflowing anything.
