mk/subst.mk: avoid undefined behavior in regular expressions
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html
says in section 9.3.2 BRE Ordinary Characters that only very few
characters may be preceded with a backslash.
As a side effect, this change allows parentheses in the variable names
listed in SUBST_VARS (even if that will never happen in practice).
The reason that the regression test had not replaced VAR.[] before was
simply that this variable had not been listed in SUBST_VARS.
