head: with --bytes=-N only allocate memory as needed
* src/head.c (elide_tail_bytes_pipe): Don't use calloc as that
bypasses memory overcommit due to the zeroing requirement.
Also realloc rather than malloc the pointer array to avoid
dependence on overcommit entirely.
* tests/misc/head-c.sh: Add a test case.
Fixes http://bugs.gnu.org/13530
