[PATCH v2 0/2] efi_loader: correct reported length in GetNextVariable()

The runtime service GetNextVariable() returns the length of the next
variable including the closing 0x0000. This length should be in bytes.

Comparing the output of EDK2 and U-Boot shows that this is currently not
correctly implemented:

OsIndicationsSupported: 46
PlatformLang: 26
PlatformLangCodes: 36

OsIndicationsSupported: 23
PlatformLang: 13
PlatformLangCodes: 18

Provide correct length in GetNextVariable().

	correct return value of the initial call too
	increase buffer size for variable names in unit test

  efi_loader: correct reported length in GetNextVariable()
  efi_selftest: check length report by GetNextVariableName()
