perf expr: Allow numbers to be followed by a dot
Metrics like UNC_M_POWER_SELF_REFRESH encode 100 as "100." and
consequently the 100 is treated as a symbol. Alter the regular
expression to allow the dot to be before or after the number.
Note, this passed the pmu-events test as that tests the validity of a
number using strtod rather than lex code. strtod allows the dot after.
Add a test for this behavior.
