Add support of optional shortname for parameter 'type' of gpt
command (limited by UUID_STR_LEN) and a separate 'description'
for UID format "%pUs" used in 'part list' output.
When 'description' is absent in list_guid[], the optional
shortname is used as fallback.
Many partition types for EFI have no shortcut yet, but only
description as they are only used to display information.
This patch also restores the "system" as short name for EFI
System Partition (ESP).
Fixes: d54e1004b8b1 ("lib/uuid.c: use unique name for PARTITION_SYSTEM_GUID")
Tested-by: Patrice Chotard <patrice.chot...@foss.st.com>
Signed-off-by: Patrick Delaunay <patrick.delau...@foss.st.com>

Changes in v2:
- change 'string' to 'type' in struct for list_guid[]
- clarify the usage of struct field 'type' and 'description' in
comment and in commit message
- use 'type' for EFI_XXX description as these string have
no space and size is lower than 36 characters.
- update after V1 review
