deps: fix libunwind build with GCC < 11 (#58628)
Apply patch from libunwind/libunwind#853 to add missing parameter names
in _UPT_ptrauth_insn_mask function to comply with ISO/IEC 9899.
Prior to GCC 11, omitting parameter names in function definitions
was an error. GCC 11 changed this behavior in commit
https://gcc.gnu.org/pipermail/gcc-cvs/2020-October/336068.html
to allow omitted parameter names as a C2x extension, making it
a pedantic warning instead of an error.
Since we build without -Wpedantic, the code compiles fine with
GCC 11+ but fails with older GCC versions.
