Fix "[compiler-rt] Allow 3 simultaneous interceptors on Linux"

Fix inline asm trampoline type. Some architectures will complain:

<inline asm>:8:41: error: expected STT_<TYPE_IN_UPPER_CASE>, '#<type>', '%<type>' or "<type>"
    8 | .type  __interceptor_trampoline_malloc, @function

Just use %function instead, which is what is also used in
sanitizer_asm.h
