Subject: NetworkPkg/HttpBootDxe: make file extension check case-insensitive

https://bugzilla.tianocore.org/show_bug.cgi?id=3694

HttpBootCheckImageType() was using the case-sensitive AsciiStrCmp() to
check the file extensions and this could reject the images with
upper-case file names. Using the case-insensitive AsciiStriCmp() to
avoid the issue.
