scripts/gen_symbol_header.awk: undefine libc symbol aliases
Avoid libc's symbol rename via #define. musl defines aliases as:
#define mkstemp64 mkstemp
#define mkstemps64 mkstemps
This causes libsandbox's aliases to clash with one another,
like mkstemp and mkstemp64.
The change does not break glibc and restores musl support.
