boot tool: fix grep misinterpretation of arguments starting with a hyphen

Browse Source 
`proxmox-boot-tool kernel remove --help`, or any version agrument
that started with a '-', lead to the grep usage message being written
into /etc/kernel/proxmox-boot-manual-kernels. The problem was `grep`
interpreted the kernel version agrument as an option since it starts
with '-'.
