Fix minor issues with CEDET on MS-Windows

* lisp/cedet/semantic/symref/idutils.el
(semantic-symref-parse-tool-output-one-line): Fix the search
regexp to match MS-Windows file names with drive letters.
(Bug#19468)
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep-use-template): Remove "--color=always" from
Grep switches on MS-Windows.
(semantic-symref-grep-shell): Use shell-file-name as the default
value, so this works not only on Posix platforms.
(semantic-symref-perform-search): Use shell-quote-argument instead
of literal '..' for portable quoting of Grep command-line
argument.  Use shell-command-switch instead of a literal "-c".
* lisp/cedet/semantic/bovine/gcc.el
(semantic-gcc-get-include-paths): Use file-name-absolute-p to test
for an absolute file name in a portable way.
