perf arm64: Use max_nr to define SYSCALLTBL_ARM64_MAX_ID
Like x86, powerpc, mips and s390, use max_nr which is a digital number to define SYSCALLTBL_ARM64_MAX_ID.

perf arm64: Handle __NR3264_ prefixed syscall number
After commit 9854e7ad35fe ("perf arm64: Simplify mksyscalltbl"), in the generated syscall table file syscalls.c, there exist some __NR3264_ prefixed syscall numbers such as [__NR3264_ftruncate], it looks like not so good, just do some small filter operations to handle __NR3264_ prefixed syscall number as a digital number.
Without this patch:
[__NR3264_ftruncate] = "ftruncate",
With this patch:
[46] = "ftruncate",

perf arm64: Rename create_table_from_c() to create_sc_table()
After commit 9854e7ad35fecf30 ("perf arm64: Simplify mksyscalltbl") it has been removed the temporary C program and used shell to generate syscall table, so let us rename create_table_from_c() to create_sc_table() to avoid confusion.
