[Buildroot] [PATCH] package/brcm-patchram-plus: fix build w/ gcc-15

[Peter Korsgaard]

Fixes http://autobuild.buildroot.net/results/2058934e442c0b3f3d0bd81bd7ed080c2eaade31/

The source code uses empty argument function pointer prototypes, which
changed behaviour in C23 (default in gcc-15):

https://gcc.gnu.org/gcc-15/porting_to.html#c23-fn-decls-without-parameters

Causing build issues. Fix it by forcing gnu99 mode instead.
