fix: find tab-indented batocera-systems entries

The entry pattern required four spaces of indent. EmuELEC indents 23 systems with one tab, so render appended each again whole and the published export carried 21 duplicated keys, the md5 fills only in the second copy. Any indent opens an entry now, and an entry written again keeps its own. The EmuELEC export is regenerated: one copy of each system, the amiga entry also gaining the eight WHDLoad Kickstarts the profiles added since 2026-10-22.
