[PATCH, applied] writer: escape enum linkage name in abixml

[Dodji Seketeli <dodji@redhat.com>]

Hello,

While looking at something else, I stumbled across this bug where the
linkage name of enum are not escaped in abixml.  So "forbidden"
characters like '<' can snick in.

Fixed thus.

This helps address https://bugzilla.redhat.com/show_bug.cgi?id=1951501

	* src/abg-writer.cc (write_enum_type_decl): Escape linkage name.

Signed-off-by: Dodji Seketeli <dodji@redhat.com>
Applied to master.
