tools headers UAPI: Sync linux/fscrypt.h with the kernel sources

To pick the changes from:

  3ceb6543e9cf6ed8 ("fscrypt: remove kernel-internal constants from UAPI header")

That don't result in any changes in tooling, just addressing this perf
build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/fscrypt.h' differs from latest version at 'include/uapi/linux/fscrypt.h'
