package/dump1090: fix build w/ gcc-15

Browse Source 
Fixes https://autobuild.buildroot.org/results/dbf55d0fd8d779f408e7ccca4c2a9083e7a11f6a/

GCC-15 has gained a new warning about non-NUL terminated strings and
dump1090 is built with -Werror leading to build errors like:

interactive.c:143:23: error: initializer-string for array of 'char' truncates
 NUL terminator but destination lacks 'nonstring' attribute (5 chars into 4
 available) [-Werror=unterminated-string-initialization]
  143 |     char spinner[4] = "|/-\\";

Add a patch from an upstream pull request to fix this by zero terminating
the strings.
