Some lscpu flags need an alias

[alexKrauseTUD]

When the TSL is generated, the required compiler arguments are derived from the lscpu list; either trhough py-cpuinfo or lscpu.

However, some flags have no direct mapping to compiler flags, especially avx512 flags, e.g.	lscpu	g++/clang
avx512_fp16	-mavx512fp16
avx512_vpopcntdq	-mavx512vpopcntdq
avx512_vbmi2	-mavx512vbmi2

Maybe we can conventionally just remove the underscores, but this might not be true for all flags.
