tmparse: remove incorrect isalpha definition
Checking the range of c|0x60 incorrectly classifies many characters
as alphabetic (digits, control characters 0x01-0x20, and punctuation
characters '!'-':'). This prevents tmparse from parsing dates with
a timezone bounded by those characters (for example, "12:11:56 (PDT)").
Instead, just reuse the isalpha macro provided by ctype.h.
