Fix Carthage build errors on case-sensitive filesystem

[mkistler]

SQLite fails to build with Carthage on Macs with case sensitive file system. The build fails with:

The following build commands failed:
    ProcessInfoPlistFile /Users/mkistler/Library/Developer/Xcode/DerivedData/SQLite-fciegensodowgvfsgoskujfmqkpa/Build/Products/Release/SQLite.framework/Versions/A/Resources/Info.plist SQlite/Info.plist
(1 failure)
error: could not read data from '/Users/mkistler/Projects/myproj/Carthage/Checkouts/SQLite.swift/SQlite/Info.plist': The file “Info.plist” couldn’t be opened because there is no such file.
A shell task failed with exit code 65:
** BUILD FAILED **

The nut of the problem is that the "L" in "SQLite" must be capitalized or the build will fail on Macs that have case-sensitive filesystems.
