[Buildroot] [git commit] package/fluidsynth: security bump to version 2.5.7

commit: https://gitlab.com/buildroot.org/buildroot/-/commit/566bdcb97f5706aa08f40a88e4728e4a0bed8257
branch: https://gitlab.com/buildroot.org/buildroot/-/tree/master

For change log since v2.4.7, see:
https://github.com/FluidSynth/fluidsynth/releases

According to:
https://github.com/FluidSynth/fluidsynth/blob/master/doc/wiki/ChangeLog.md

FluidSynth 2.5.6 fixes:
CVE-2026-58264 - a heap-based buffer overrun in command handler (GHSA-mqmq-w63q-cj94)
CVE-2026-61714 - a heap-based buffer overflow in MIDI player (GHSA-976m-35rw-h3m6)
CVE-2026-61721 - a heap-based buffer overrun for DLS samples (GHSA-59ph-rx8r-8p4j)
CVE-2026-61723 - a DLS ptbl chunk integer overflow (GHSA-r4mc-v3p8-pv47)
CVE-2026-61722 - a DLS articulation chunk integer overflow (GHSA-hp72-35pr-6h6r)
CVE-2026-61720 - a SF2 DMOD chunk integer underflow (GHSA-rmc4-c8hw-455w)

FluidSynth 2.5.2 fixes:
CVE-2025-68617 - a heap-based use-after-free involving DLS files (GHSA-ffw2-xvvp-39ch)

SDL2 audio support was removed upstream in commit:
https://github.com/FluidSynth/fluidsynth/commit/89145b004a44a53e734b6bf82a73cef255baef5d

It was replaced by the newer SDL3. This commit reflects that change
(update option name and comments, add legacy option entry).

Also, dynamic library dependency was added in Buildroot commit:
https://gitlab.com/buildroot.org/buildroot/-/commit/111a1c7091aed6f9da03c2a095bcc2f50a1ad32c
This commot removes the duplicate dependency for SDL3.

FluidSynth also added a native DLS soundfont support in:
https://github.com/FluidSynth/fluidsynth/commit/c959f8d208bbad9e396dfb745285806b5a4c5a07
It is enabled by default and uses C++17. This commit adds a new
option with a dependency on gcc >= 7.

The license option hash is also updated, after the FSF address
update in:
https://github.com/FluidSynth/fluidsynth/commit/db42fa333baf1cb7c60556ab75ad1e592c850f68
