Replace obsolete <sys/fcntl.h> with <fcntl.h>

The standard location <fcntl.h> instead of <sys/fcntl.h> is the
preferred one since a long time (Changelog.old mentions this change
being made in 1996).

This patch fixes the two occurrences that have slipped through, making
the includes consistent with other files in dpkg as well as fixing
compiling on e.g. Android which lacks <sys/fcntl.h>.

Closes: #752036
