[Buildroot] [PATCH] package/tftpd: bump to version 5.4

[Nathan Bloch <nblochn@gmail.com>]

Switch from a post-5.3 git snapshot back to the release tarball, now
that 5.4 is out.

This also fixes a regression in the snapshot we pin: the autoconf
modernization in fefaa2cc5c2a renamed the msg_control define to
HAVE_STRUCT_MSGHDR_MSG_CONTROL, but tftpd/recvfrom.c kept testing for
HAVE_MSGHDR_MSG_CONTROL, so the recvmsg() code path is compiled out and
the fallback is used instead. That fallback reads the address family
from the 'from' address before recvfrom() has filled it in, so the
first request after each start creates the transfer socket with
AF_UNSPEC, gets EAFNOSUPPORT and exits without answering or logging the
request. Fixed upstream in 5.4 by e701714f7a8c ("autoconf: correct the
new #define names after modernization") and 82223bbf9391 ("tftpd/
recvfrom.c: don't derive local address family before recvfrom()").

Drop TFTPD_AUTORECONF and its m4 include directory: the release tarball
ships a configure script.

Update the license information: 5.4 replaced the per-file license
preambles with SPDX tags and a LICENSES/ directory, so tftpd/tftpd.c no
longer contains any license text. Both binaries are built from a mix of
BSD-4-Clause-UC and BSD-3-Clause files.

Add a patch for the only build failure in 5.4: tftpd/path.h uses bool
without including <stdbool.h>, which requires a C23 compiler.

Fixes: d4a84e61615553ff678d3c3b52ed33f898e9fcc9

+Subject: [PATCH] tftpd/path.h: add missing <stdbool.h> include
+
+path.h declares parse_path() with a bool parameter, and both of its
+users, path.c and tftpd.c, use bool without including <stdbool.h>
+themselves. That only compiles where bool is a keyword, i.e. C23, so
+the build fails with any compiler defaulting to C17 or older:
+
+  path.h:7:43: error: unknown type name 'bool'
+  path.c:55:33: error: 'true' undeclared (first use in this function)
+  tftpd.c:391:5: error: unknown type name 'bool'
+
+gcc defaults to gnu17 up to and including 14.x, so 5.4 does not build
+with any of them.
+
+Include <stdbool.h> from path.h, the header declaring the bool-taking
+prototype, which both users already include.
+
+Upstream: not submitted yet, upstream master is affected as well.
