[pmg-devel] [PATCH pmg-api] utils: custom check: fix error in spamscore regex

[Stoiko Ivanov]

Currently a reply with a negative spam-score with fractional part like:
v1
SCORE: -1.52
yields an error (as the optional '-' is only accepted as part of the
first alternative.

quickly tested with a very minimal custom-checkscript (that returns
the output above).
