verification/rvgen: Fix suffix strip in dot2k

Browse Source 
__start_to_invariant_check() and __get_constraint_env() parse the
environment variable's name from sources that have it padded with the
monitor name. This is removed using rstrip(), which is not meant to
strip a substring but rather a set of characters.

Use removesuffix() to actually get rid of the trailing _<monitor name>.
