all.sh: export LC_COLLATE=C for sorting in ASCII order

By default, 'sort' sorts characters with system default locale,
which causes unexpected sorting order. To sort characters in ASCII
from computer perspective, export LC_COLLATE=C to specify character
collation for regular expressions and sorting with C locale.
